IllegalMonitorStateException when prepare/commit sequence happens in diff threads
---------------------------------------------------------------------------------

                 Key: ISPN-1258
                 URL: https://issues.jboss.org/browse/ISPN-1258
             Project: Infinispan
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 5.0.0.CR8
            Reporter: Galder Zamarreño
            Assignee: Mircea Markus
             Fix For: 5.0.0.FINAL


There's no guarantees at the JGroups level that in a sequence of prepare+commit calls, both will be handled by the same thread as shown in the logs:

Here's a prepare call:

{code}2011-07-20 21:01:44,400 2011  TRACE [org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher] (OOB-1,Infinispan-Cluster,NodeB-10116:) Attempting to execute command: PrepareCommand {gtx=GlobalTransaction:<NodeA-32281>:1:local, modifications=[PutKeyValueCommand{key=a, value=value1, flags=null, putIfAbsent=false, lifespanMillis=-1, maxIdleTimeMillis=-1}], onePhaseCommit=false, gtx=GlobalTransaction:<NodeA-32281>:1:local, cacheName='cache1'} [sender=NodeA-32281]

And the commit:

{code}2011-07-20 21:01:44,418 2029  TRACE [org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher] (OOB-2,Infinispan-Cluster,NodeB-10116:) Attempting to execute command: CommitCommand {gtx=GlobalTransaction:<NodeA-32281>:1:local, cacheName='cache1'} [sender=NodeA-32281]

The end result?

{code}

Mircea, could you have a look?
