Richard Janík commented on ISPN-8990:
-------------------------------------

Oh, so I just received a forwarded mail with the information that this is gone in 9.x because the marshaller/unmarshaller types are different (no longer JBoss Marshaller). So this can probably be closed.

> 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.
