Mattias Jiderhamn commented on JGRP-1576:
-----------------------------------------
I don't have an isolated test case.
The problem appeared when using JGroups behind Infinispan for clustered Hibernate Search /
Lucene. I have little insight into how Infinispan uses JGroups, but I could upload the
config files if that helps?
org.jgroups.protocols.TP.ChannelThreadGroup leaks classloaders /
PermGen memory
-------------------------------------------------------------------------------
Key: JGRP-1576
URL: https://issues.jboss.org/browse/JGRP-1576
Project: JGroups
Issue Type: Feature Request
Affects Versions: 3.2.5
Reporter: Mattias Jiderhamn
Assignee: Bela Ban
Fix For: 3.2.7
Just like JGRP-1410 there is a custom ThreadGroup
org.jgroups.protocols.TP.ChannelThreadGroup which is not destroyed so the parent thread
group will keep a reference and keep the classloader from being garbage collected. There
is actually code for destroying the thread groups (line 1026-1030) but for some reason it
is commented out.
