RFR: 8335121: Native memory leak when not recording any events

Thu Aug 1 21:17:56 UTC 2024

Greetings,

This minor adjustment prevents thread metadata memory from growing continuously when JFR does not record any events. A recording is running, meaning new threads will register their metadata. However, since no events are generated, metadata processing, including deallocation, is skipped. This is an old optimization that is no longer valid and is, therefore, removed.

Testing: jdk_jfr

Thanks
Markus
