Resolution

======= 

The workaround is to add " AND " at the end of the selector string that is used in the JMS Queue Receiver or Wait for JMS Queue Message activities. For example, if the selector used in Wait for JMS Queue Message activity is “JMSCorrelationID='%%RvService%%'” (without the double quotes), you need to use “JMSCorrelationID='%%RvService%%" AND " (without the double quotes). Note there is a space before and after AND .
