[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-3236) Prevent classloader leaks to JBC and JGroups when using a shared cache

Prevent classloader leaks to JBC and JGroups when using a shared cache ---------------------------------------------------------------------- Key: HHH-3236 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3236 Project: Hibernate Core Issue Type: Sub-task Components: caching (L2) Reporter: Brian Stansberry JGroups spawns a number of threads when a channel is created. JBC can spawn an eviction thread as well. A newly spawned thread inherits its thread context classloader from the thread that spawned it. If a shared JBC CacheManager is used (e.g. in an appserver) it is important to set the TCCL away from any application classloader and to the CacheManager's TCCL before starting a cache. This ensures that the application classloader doesn't leak to any JBC or JGroups threads.
