This is a bug in the JMS client (LISA JMS Client). JMS properties defined as Boolean are passed as String, hence the ClassCastException since the property is defined as Boolean in the Event artifact in BusinessEvents Studio.
This issue related to the JMS client and is not a TIBCO BusinessEvents issue. As an alternative use BW , JMeter or HermesJMS  as a JMS client.
