> Key: FLINK-25002
> URL: https://issues.apache.org/jira/browse/FLINK-25002
> Project: Flink
> Issue Type: Sub-task
> Components: Build System, Build System / CI, Documentation, Tests
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.18.0

>
> Java 17 actually enforces the encapsulation of the JDK (opposed to Java 11
> which just printed warnings), requiring us to explicitly open/export any
> package that we access illegally.
> The following is a list of opens/exports that I needed to get most tests to
> pass, also with some comments which component needed them. Overall the
> ClosureCleaner and FieldSerializer result in the most offenses, as they try
> to access private fields.
> These properties need to be set _for all JVMs in which we run Flink_,
> including surefire forks, other tests processes
> (TestJvmProcess/TestProcessBuilder/Yarn) and the distribution.
> This needs some thought on how we can share this list across poms (surefire),
> code (test processes / yarn) and the configuration (distribution).
