Subject org.apache.activemq.openwire.v2.BaseDataStreamMarshaller error
Date Mon, 23 Apr 2007 12:57:52 GMT

Sometime in an aplication I develop using ActiveMQ I get an error. It appears
quite "random" and not very often
Here is a stack:
Exception in thread "ActiveMQ Task" java.lang.NullPointerException

I use the version 4.1.1 and the url is
tcp://localhost:61616?wireFormat.maxInactivityDuration=300000. I think I
didn't seen this error before updating the activeMQ version but quite the
same time I extended the maxInactivityDuration

Any idea what it can be?
