General Information
OpenJDK 17 updates will be delivered on the same established quarterly cycle used by Oracle i.e. "the third Tuesday of January, April, July and October."
...
In addition to this list, we will consider
- Build system improvements, particularly for stability and reproducibility
- Changes necessary to make 17u work on new operating systems and hardware
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 if you are in any doubt about whether your proposed backport might qualify.
...
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.
