Hi all,

I am using logback 0.9.9 with activemq 5.5.1.  Right after startup, the application always encounters an AbstractMethodException in LogbackMDCAdapter, which is firstly triggered by  PooledTaskRunner (line 45).  A snippet is provided as:


public static void main(String[] args) {
MDCAdapter l = StaticMDCBinder.SINGLETON.getMDCA();
Map m = l.getCopyOfContextMap();  // <-- got excpetion
System.out.println("np error"); // never come to this line
}



Seems that the concrete class LogbackMDCAdapter implements MDCAdapter without implementing the defined method getCopyOfContextMap().  


Any clues?

Thanks,
Hei
