Hi Hei, If you look at MDCAdapter javadocs [1], you will see that the getCopyOfContextMap method was introduced in slf4j version 1.5.1. Logback-classic version 0.9.9 targets an earlier SLF4J version, i.e v1.5.0. Try using logback version 0.9.10 or later and the problem will go away.

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
