Fix potential memory leak in InMemoryReadWriteLockConnectionStore #2284

Closed zakersimonjack closed 1 day ago

zakersimonjack commented 1 day ago

During our stress test, I noticed that memory usage kept going up and didn't decrease significantly after GC.

Then I checked the classes in memory. The Connection class in connectionsByPrincipal never seems to get cleaned up. Finally I found removeByPrincipal seems to be missed in onEviction of EvictionListener.

My current plan is to release 3.13 on Wednesday, 9. October. (I will do the orga work for 3.13 and schedule tomorrow.) Just in the case your stress test uncovers more, let me know.
