UnlockedSharedObjectException in ehcache management
---------------------------------------------------
Key: CDV-585
URL: https://jira.terracotta.org/jira//browse/CDV-585
Project: Community Development
Issue Type: Bug
Affects Versions: 2.5.0
Reporter: Tim Eck
Assignee: Issue Review Board
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);
This is the exception text:
com.tc.object.tx.UnlockedSharedObjectException:
*******************************************************************************
Attempt to access a shared object outside the scope of a shared lock.
All access to shared objects must be within the scope of one or more shared
locks defined in your Terracotta configuration.
Please alter the locks section of your Terracotta configuration so that this
access is auto-locked or protected by a named lock.
