[logback-user] AbstractMethodError in LogbackMDCAdapter

[ceki]

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.
