Hi all,
While I testing ESB samples found that JMS transport does not works with
activeMQ 5.5.0 ( latest) JMS client jars, but works with pre 5.5.0 versions
( >=5.4.2 ...... )
here is startup log.
[2011-05-09 10:22:33,556] INFO - JMSListener JMS listener started

and this exception continuously prints until ESB stopped.
reason might be different slf4j versions used in activeMQ and carbon,

../soapui-3.6.1/lib/slf4j-api-1.5.8.jar
Any idea about how to support activeMQ 5.5.0?
One possible workaround that I found is, we can use 5.4.2 activeMQ libs with
5.5.0 broker.
