question: protected void handleException ( JMSException je ) { if ( endTime == 0 ) { endTime = System . currentTimeMillis ( ) ; } Exception le = je . getLinkedException ( ) ; Throwable t = je . getCause ( ) ; if ( ( null == t ) && ( null != le ) && ( t != le ) ) { je . initCause ( le ) ; } handleException ( ( Exception ) je ) ; }
target:  Overloaded method to cross-link JDK 1.4 initCause and JMS 1.1 linkedException if it has not already been done by the JMS vendor implementation.
