Summary: Rollinglogged PM can throw NullPointerException
Initial Comment:
I got this when moving a failed message from the Dead
Letter Queue (DLQ) back to the original queue.
There is probably a bug in the PM:

The NPE occurs on
synchronized(logs)
protected void checkCleanup(SpyTxLog txLog) throws
JMSException
{
if (txLog == null || txLog == currentTxLog)
{
return;
}
HashMap logs;
synchronized (messageLogs)
{
logs = (HashMap)messageLogs.get(txLog);
}
synchronized (logs)
{
If the transaction has gone missing, probably nothing
should be done -- I suggest logging a warning at the
very most.

I checked in a fix -- should double-check sync blocks in
this class.

I've reproduced this again ... I am assuming there is a race
condition someplace, but the cleanup code (at the very
least) shouldn't do this.
