Mark Struberg resolved TOMEE-217.
---------------------------------
Resolution: Not A Problem
moving log4j.jar into the common catalina ./lib folder did solve the problem.
Guess that was our persistence.xml configuration where we tell OpenJPA to use
log4j. This most probably happens due to openjpa being on the container
classpath and Catalinas WebAppClassLoader prevents overriding/referencing any
classes 'upwards' if the loading got initiated from a system CL (even if the
TCCL can see the other class).
