That is interesting. It shows the context waiting to be notified for a
transaction
conflict to resolve. I have found the problem with the NPE that is showing
up in
the bank unit test and in the process I see some problems with how the
context
transaction is being handled. This is a piece that Marc just totally rewrote
and it
still has some bugs in it.
Send me the full thread dump directly to me so I can see if it shows anyone
holding
the monitor. Send it to [EMAIL PROTECTED]
