[jboss-jira] [JBoss JIRA] Created: (JBCACHE-1212) ClassNotFoundException when connecting to exisiting cache

ClassNotFoundException when connecting to exisiting cache --------------------------------------------------------- Key: JBCACHE-1212 URL: http://jira.jboss.com/jira/browse/JBCACHE-1212 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.0.0.GA Environment: Java 1.6.0_02; dependencies according to POM, except JGroups 2.5.0GA; Win XP SP2 fully patched Reporter: Carl Shelbourne Assigned To: Manik Surtani When running internal tests for our application we spotted the following exceptions. The method within our code, _remove() provides a simple check before removing from the cache: ... protected void _remove( final Fqn fqn ) throws CacheException { if ( getTreeCache().getRoot().hasChild( fqn ) ) { getTreeCache().removeNode( fqn ); getFqnList().remove( fqn ); } } ... All the code appears to work ok, with the exception of when a we try to connect to an existing cache, from observations, once the cache is started we seem to get this exception. It is difficult to establish the exact cause, but it seems that a remove has been called before all the classes are instantiated??? Not sure, sorry.
