[infinispan-issues] [JBoss JIRA] (ISPN-8974) Avoid JBossMarshaller instance caches growing limitless

Avoid JBossMarshaller instance caches growing limitless ------------------------------------------------------- Key: ISPN-8974 URL: https://issues.jboss.org/browse/ISPN-8974 Project: Infinispan Issue Type: Bug Components: Marshalling Affects Versions: 8.2.10.Final Reporter: Galder Zamarreño Assignee: Galder Zamarreño Labels: downstream_dependency Fix For: 8.2.11.Final In the 8.2.x design, JBoss Marshaller marshaller/unmarshaller instances were cached in thread locals to speed up things. Internally it instance caches are kept which never shrink. This can create leaks. We should change the code so that when releasing marshallers/unmarshaller, if instance cache is bigger than certain size, destroy the marshaller and let it recreate it. A good size to not go beyond would be 1024, given that in 8.2.x we configure JBoss Marshaller instance count to 32. This would require Infinispan code to access and check instance cache size.
