Welcome to OpenJDK 17 Updates!

...


OpenJDK 17 updates are part of the JDK updates project of the OpenJDK. Rob McKenna serves as the Project Lead. The list of Reviewers, Committers, and Authors can be found in the jdk updates section of the OpenJDK Census.

...

OpenJDK 17 updates will be delivered on the same established quarterly cycle used by Oracle i.e. "the third Tuesday closest to the 17th day of January, April, July and October."

...

In general we follow the common rules for the jdk-updates project. 

In addition to this list, we will consider

...

However, if there is an enhancement that provides substantial benefit to OpenJDK 17u users and it is of low risk, we will consider it. Please ask on the jdk-updates mailing list mailing list if  if you are in any doubt about whether your proposed backport might qualify.

...

Push approval for a fix is requested by setting the jdk17u-fix-request label on the original JBS bug. The maintainers will either approve by setting jdk17u-fix-yes or reject by setting jdk17u-fix-no. Outstanding approvals can be monitored here TODO. If and only if the fix gets approved, it may be pushed to the jdk17u-dev repository. Approved fixes show up in this JBS filter TODO (login required).

During the later stages of a release cycle, the release enters rampdown. The master jdk17u repository contains the latest version of that release, while the jdk17u-dev repository is used to start work on the next release. If a change needs to be pushed to a release in rampdown, push approval can still be requested using the jdk17u-critical-request label. As the name of this tag suggests, this process is intended for fixes such as major regressions that must make the release. More minor bugs and new features should go in the next release being developed in jdk17u-dev. The maintainers may approve with jdk17u-critical-yes, defer to jdk17u-dev or reject altogether. Outstanding approvals for critical fixes can be monitored here TODO . If, and only if, the fix gets approved with jdk17u-critical-yes, it may be pushed to the jdk17u repository. Approved critical fixes show up in this JBS filter TODO (login required).

At the end of the month prior to the release month, the jdk17u repository is declared frozen so embargoed security fixes can be added in private during the final few weeks. On release day, the final version will be pushed to the jdk17u repository and source bundles made available.

...

jdk17u-dev: Always open repository for development of upcoming JDK 17 Update releases. Pushes after jdk17u-fix-yes approval. Check here TODO for clearance.

jdk17u: Repository used for Rampdown of JDK 17 Update releases. Pushes only during 4-weeks rampdown period after jdk17u-critical-yes approval. Check here TODO for clearance.

Timelines

The release date follows the schedule of Oracle Critical Patch Updates as this is the date embargoed security fixes can be published.

Common jdk17u JBS labels

The above filters exclude issues that are marked with the following labels:

  • jdk17u-na Change does not apply to open jdk17u. In general, this is a change done by Oracle for their build or test infrastructure, for their own delivery or in their tests not open sourced. Any other change can also be not of interest to open jdk17u.
  • jdk17u-defer-next Change is generally acceptable, but should go into the next JDK 17 update release. I.e. 17.0.4 is currently collecting fixes in jdk17u-dev, but the proposed change should get into 17.0.5 (the next release) instead.  The maintainers will clear this label when development of the next release (17.0.5 in the example) is started.
  • jdk17u-todo Changes Oracle backported to older releases that are not backported to open jdk17u.  We mostly need this tag to make the "all" filters more efficient.
