Chesnay Schepler closed FLINK-25006.
------------------------------------
Resolution: Invalid
This was caused by missing module declarations that threw tests into hot loops.
> Investigate memory issues on CI

> Key: FLINK-25006
> URL: https://issues.apache.org/jira/browse/FLINK-25006
> Project: Flink
> Issue Type: Sub-task
> Components: Build System / CI
> Reporter: Chesnay Schepler
> Priority: Major
>
> During my tests with Java 17 I noticed significant speed regressions in tests
> that actually run jobs, to the point where they effectively stalled. If they
> managed to complete, then subsequent tests would also experience a
> significant slowdown.
> As an experiment I disable fork reuse, which very quickly resulted in direct
> memory OOMs.
> We need to investigate what is going on. I can provide logs and a branch with
> Java 17 to anyone who is interested.
