We're getting a JMS error which we don't have a lot to go with:

org.springframework.jms.UncategorizedJmsException: Uncategorized exception occured during JMS processing; nested exception is weblogic.jms.common.JMSException:[JMSClientExceptions:055039] A system error has occurred.

The only lead I have is line 127 in the code which is indicated by this error:

This is line 127:

try {
    Thread.yield();
    //line 127 below
    status=(StatusMessageBean)getJmsTemplate.receiveSelectedAndConvert(statusDestination, "JMSCorrelationID='"+ producerMsg.getProcessID() +"'");
    Thread.yield();
} catch (Exception e) {
    Thread.yield();
    loggingInterface.doErrorLogging(e.fillInStackTrace());          
}       

According to the BEA documentation, we should contact BEA about error 055039 but I would like to try asking here first before bringing this to them?
