2) A whole raft of NullPointer exceptions.
As soon as we see one of these, we'll keep getting more until we stop
and restart xmlblaster. Up until then though, all is well.
We have applied a patch now.
Could you please confirm that it fixes your NPEs?
Anyhow: Could you please send me more details what sort of messages
caused this behavior
(volatile ? persistent ?)
regards
Marcel
