ClassCastException, BrokerId

Hi all!

Anyone have seen this exception in 4.1.0? I only use Java clients to
commincate with AMQ. Any ideas?

I get a lot of "org.apache.activemq.transport.InactivityIOException: Channel
was inactive for too long" messages before and after the ClassCastException.

I have spring jar from amq 4.0.1 distribution (I think spring 1.2.8), but amq
jar is 4.1. Thanks.

Could be that you have client jars with different version than the 
broker? I'm not really sure though...
