[jboss-dev-forums] [Design of JBossCache] - Re: JBCACHE-1025: JBossCache mbean registration fails on Web

[JerryGauth]

I've just discovered a related issue when JBossCache isn't configured as a JBoss service.  This issue applies when running on JBossAS as well as other servers.

Suppose my cache's lifecycle is as follows.

TreeCache cache = new TreeCache();
cache.start();
...  // use the cache
cache.stop();
cache.destroy();

The start() method invocation will cause the cache's mbeans to be registered, assuming registration is enabled.

The destroy() method invocation should deregister the mbeans that were previously registered.  However this isn't occurring when the cache is created as noted.  When running on JBossAS, the following messages are emitted to the log and cache.destroyService() is never invoked so deregistration never occurs.

10:21:51,053 WARN  [ServiceController] Ignoring request to stop nonexistent service: jboss.cache:service=TreeCache-Group
10:21:51,053 WARN  [ServiceController] Ignoring request to destroy nonexistent service: jboss.cache:service=TreeCache-Group

It appears that the cache client must explicitly invoke cache.stopService() and cache.destroyService() to ensure that the cache is shut down properly.
