RFR: 8287699: jdk/jfr/api/consumer/TestRecordingFileWrite.java fails with exception: java.lang.Exception: Found event that should not be there.

[Markus Grönlund]

Greetings,

the problem here addressed will to close a gap in the constant pool data for threads, which up to now has been written on thread start only, but not on thread end. This leads to a race where a thread can write an event in a new chunk and terminate, before the JFR recorder thread has had a chance to iterate it. By also writing constant pool data for threads on thread end, we close this gap.

Testing: jdk_jfr, stress testing

Thanks
Markus
