    source: http://forums.terracotta.org/forums/posts/list/723.page If one takes a clustered ehcache CacheManager instance and try to register it with an MBeanServer, you'll get an UnlockedSharedObjectException. Making a call like this (passing a shared cacheManager) should produce the issue net.sf.ehcache.management.ManagementService.registerMBeans(cacheManager, ManagementFactory.getPlatformMBeanServer(), true, true, true, true); It looks like an attempt was made to make this transient since "net.sf.ehcache.CacheManager.cacheManagerEventListener" is declared transient in terracotta.xml in both the 1.2.4 and 1.3.0 modules. Unfortunately that field does not exist. Correcting the field name will just lead to an NPE on other nodes.
