Jakarta EE TCK Process 1.0
Specification Projects under the Eclipse Foundation Specification
Process MUST produce a Technology Compatibility Kit (TCK) that delivers
on the promise of enabling multiple compatible implementations.
This document defines:
Materials a TCK MUST possess to be considered suitable for
Process for challenging tests and how these challenges are resolved
Means of excluding released TCK tests from certification
Policy on improving TCK tests for released specifications
Process for self-certification
Materials for a TCK Release
Projects MUST produce the project licensed (EPL, Apache, etc.)
version for distribution to Maven Central or other open source
channels, usable for automated, non-official testing, and
implementation. No compatibility claims can be made on the basis of
Projects MUST produce a final candidate binary that includes the
EFTL license. The Jakarta
EE Specification Committee will sign and promote project TCK binary
for distribution via Eclipse infrastructure on final approval. This
is the TCK binary usable for self-certification when one desires to
make a claim of compatibility, allowing for the use of the Jakarta
Both TCK binaries MUST contain the following
We recommend that the TCK documentation include
URLs for the issue trackers to file certification requests, bug
A statement that the Certification of
Compatibility process must be
followed before a claim of compatibility can be made.
TCK binaries MAY contain
Test coverage document
Test assertion document
Release available via a release on project GitHub releases page(or
Ratifying a Final TCK
Projects will submit the EFTL proposed final binary of the TCK for
approval to the Specification Committee.
The Specification Committee will vote to approve or reject the TCK
Approved binaries will be signed with the GPG key of the Jakarta
Specification Committee, and then published on download.eclipse.org
along with the digital signature of the SHA-256 hash of the final
binary, and the SHA-256 hash of the binary as the fingerprint of the
Consumers can use the GPG key of the Jakarta Specification Committee
to verify the authenticity of that or any TCK binary.
Specifications are the sole source of truth and considered overruling to
the TCK in all senses. In the course of implementing a specification and
attempting to pass the TCK, implementations may come to the conclusion
that one or more tests or assertions do not conform to the
specification, and therefore MUST be excluded from the certification
Requests for tests to be excluded are referred to as Challenges. This
section identifies who can make challenges to the TCK, what challenges
to the TCK may be submitted, how these challenges are submitted, how and
to whom challenges are addressed.
Who can file a challenge?
Any implementor may submit a challenge to one or more tests in the TCK
as it relates to their implementation. Implementor means the entity as a
whole in charge of producing the final certified release. Challenges
filed MUST represent the consensus of that entity.
Any test case (e.g., test class, @Test method), test case configuration
(e.g., deployment descriptor), test beans, annotations, and other
resources considered part of the TCK may be challenged.
The following scenarios are considered in scope for test challenges:
Claims that a test assertion conflicts with the specification.
Claims that a test asserts requirements over and above that of the
Claims that an assertion of the specification is not sufficiently
Claims that a test is not portable or depends on a particular
The following scenarios are considered out of scope for test challenges
and will be immediately closed if filed:
Challenging an implementation’s claim of passing a test.
Certification is an honor system and these issues MUST be raised
directly with the implementation.
Challenging the usefulness of a specification requirement. The
challenge process cannot be used to bypass the specification process
and raise in question the need or relevance of a specification
Claims the TCK is inadequate or missing assertions required by the
specification. See the Improvement section, which is outside the
scope of test challenges.
Challenges that do not represent a consensus of the implementing
community will be closed. If agreement is later reached by the
implementing community, the issue can be reopened. The test
challenge process is not the place for implementations to initiate
their own internal discussions.
Challenges to tests that are already excluded for any reason.
Challenges that an excluded test should not have been excluded and
SHOULD be re-added MUST be opened as a new enhancement request
Filing a Challenge
Challenges MUST be filed via the specification project’s issue tracker
using the label
challenge and include the following information:
The relevant specification version and section number(s)
The coordinates of the challenged test(s)
The exact TCK version
The implementation being tested, including name and company
A full description of why the test is invalid and what the correct
behavior is believed to be
Any supporting material; debug logs, test output, test logs, run
Challenges can be resolved by a specification project lead, or a project
challenge triage team, after a consensus of the specification project
committers is reached or attempts to gain consensus fails. Specification
projects may exercise lazy consensus, voting or any practice that
follows the principles of Eclipse Foundation Development
The failure to resolve a Challenge might prevent an implementation from
going to market; Challenges SHOULD be given a high priority by the
specification project and resolved in a timely manner. Two weeks or less
SHOULD be considered the ideal period of time to resolve a challenge.
Challenges may go longer as needed, but as a rule SHOULD avoid months.
If consensus cannot be reached by the specification project for a
prolonged period of time, the default recommendation is to exclude the
tests and address the dispute in a future revision of the specification.
A consensus that a test produces invalid results will result in the
exclusion of that test from certification requirements, and an immediate
update and release of an official distribution of the TCK including the
new exclude list. The associated
challenge issue MUST be closed with
accepted label to indicate it has been resolved.
Rejected Challenges and Remedy
challenge issue is rejected, it MUST be closed with a label of
invalid to indicate it has been rejected. The appeal process for
challenges rejected on technical terms is outlined in Escalation Appeal.
If, however, an implementer feels the TCK challenge process was not
followed, an appeal issue MUST be filed with the specification project’s
issue tracker using the label
challenge-appeal. A project lead MUST
escalate the issue with the Jakarta EE Specification Committee via email
(firstname.lastname@example.org). The committee will evaluate the matter
purely in terms of due process. If the appeal is accepted, the original
TCK challenge issue will be reopened and a label of
added, along with a discussion of the appeal decision, and the
challenge-appeal issue with be closed. If the appeal is rejected, the
challenge-appeal issue MUST be closed with a label of
Excludes MUST be included in the TCK project release in a format that is
compatible with the testing framework in use so that as the excludes are
updated, the affected tests are automatically removed from the test
Requests for improvement to tests MUST simply be created as issues with
a label of
enhancement in the specification project’s TCK issue
Certification of Compatibility
Jakarta EE is a self-certification ecosystem. If you wish to have your
implementation listed on the official jarkarta.ee
implementations page for the given specification, a certification
request as defined in this section is required.
There are additional requirements that MUST be met by any organization
wishing to use the Jakarta EE logo or jarkarta.ee
website for promotion. Any request for certification from an
organization not meeting the requirements will be held until such time
as the requirements are met. See the Jakarta EE Trademark
Guidelines for more
information on the complete steps to obtain Jakarta EE branding usage.
An approved certification request is a statement from the Specification
Project you have met the intended TCK requirements and is just one of
the requirements for logo usage. Logos only apply to platform and
profile specifications, but a request to be listed as a compatible
implementation can be made for any specification.
Filing a Certification Request
Requests to be acknowledged as a certified implementation MUST be filed
via the specification project’s issue tracker using the label
certification and include the following information:
Statement of Acceptance of the terms of the EFTL
Product Name, Version and download URL (if applicable)
Specification Name, Version and download URL
TCK Version, digital SHA-256 fingerprint and download URL
Implementation runtime Version(s) tested
Public URL of TCK Results Summary
Any Additional Specification Certification Requirements
Java runtime used to run the implementation
Summary of the information for the certification environment,
operating system, cloud, …
A statement attesting that all TCK requirements have been met,
including any compatibility rules
Additional Specification Certification Requirements
Specification projects may require additional items for a Certification
Request as defined in their corresponding TCK Documentation under the
section labeled "Additional Certification Requirements".
Examples of such additional requirements may include:
Name and version of Compatible Implementation used for
Name and version of Databases used for persistence tests
Name and version of NoSQL implementations used in persistence tests
Public TCK Results Summary
While certification is on your honor, the community MUST be able to see
your test results summary. At a minimum a results summary MUST:
An optional “Test List Page” showing all tests run may be linked from
the Summary Page. The Summary Page URL is the URL that MUST be included
in any Certification Requests.
The following are explicitly not requirements:
Implementors may supply this information and provide support for how to
run a TCK against their implementation, but it is not required.
As noted, certification requests do not in themselves grant rights to
use the Jakarta EE logo. Approval that the TCK requirements have been
met is a prerequisite for obtaining Jakarta EE logo usage for profile
certification. The required approval processes is:
Approval by lazy consensus after a period of two weeks (14 days)
Approval by a majority vote of the specification project as soon as
- The sum of the +1/-1 votes must be greater than 50% of the
specification project committers.
Approval by any top-level specification project lead at any time
All specification project members are encouraged to review the request
and associated supporting materials. Reviewers of a certification
request MUST carefully check the validity of all required data, in
the data is complete
the number of tests passed is consistent with the first
implementation used to validate the TCK
TCK version and digital fingerprint match.
test results are public and do not require special signup or viewing
Any committer on the specification project may vote against the
certification request on the basis that the clearly defined requirements
of the TCK process have not been met. This means that if there is a (-1)
vote, lazy consensus is no longer an option and a majority vote MUST
Accepted Certification Requests
Certification requests that are reviewed and found to meet the
requirements will be marked accepted by closing an issue with an
accepted label. A pointer/link to the issue MUST then be emailed to
[email@example.com](mailto:firstname.lastname@example.org), as required by the
[Eclipse Foundation Technology Compatibility Kit
License](https://www.eclipse.org/legal/tck.php). If use of the
Jakarta EE logo or trademark is being requested (currently only
applicable to platform or profile products), see the [Jakarta EE
Rejected Certification Requests
Certification requests that are reviewed and found to NOT meet the
requirements will be marked as such by closing an issue with an
invalid label along with the requirements that were not met. A new
certification issue MUST be created with the updated requirements to
attempt the certification request again.
If there is a concern that a TCK process issue has not been resolved
satisfactorily, the Eclipse Development Process Grievance
procedure SHOULD be followed to escalate the resolution. Note that this
is not a mechanism to attempt to handle implementation specific issues.
How Tests May be Added to a TCK
The only time tests may be added to a TCK are in a major or minor
release. A service release which updates the exclude list MUST not have
test additions or changes.
