twundke updated JBCACHE-82:

Attachment: NodeIssue.txt
> Deserialized Node object doesn't have the FQN set

> Key: JBCACHE-82
> URL: http://jira.jboss.com/jira/browse/JBCACHE-82
> Project: JBoss Cache
> Type: Patch

> When a new cache starts and retrieves the transient state, Node objects are
> created--by the serialisation process--using the no-arg constructor. This
> constructor calls init(), which creates the IdentityLock object using "new
> IdentityLock(cache_,fqn)". The problem is that the fqn is never set on the
> IdentityLock (as the Node doesn't know the fqn at this point), which means
> that all IdentityLock messages show "null" as the fqn. Here's a patch on
> revision 1.60 that fixes the problem by creating the lock in readExternal()
> rather than in the constructor.
