You can view the code through CVS or download it.
What's happening, is JBoss is trying to copy/clone the correlation ID from the Weblogic JMS message and failing. As a work around, you can set this field as part of the bridge to something like an empty array. I will try to post a fix to CVS, here is the code:
public void setMessage(Message m) throws JMSException
public void setJMSCorrelationIDAsBytes(byte correlationID) throws JMSException
header.jmsCorrelationID = false;
header.jmsCorrelationIDbyte = (byte) correlationID.clone();
header.jmsCorrelationIDString = null;
