[jboss-as7-dev] [Resteasy-developers] NPE at org.jboss.resteasy.logging.Logger.classInClasspath(Logger.java:62)

[Jason T. Greene]

I don't know where call this is coming from but if its from an EE 
context TCCL should be set to the deployment CL by spec.

Here is some info though on why TCCL use should usually be avoided:
http://community.jboss.org/wiki/ModuleCompatibleClassloadingGuide

If the call is coming in from a service or a subsystem of the RestEasy 
integration then we can set it to whatever RestEasy expects it to be.
