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

[David M. Lloyd]

It is perfectly valid to have a context class loader of "null" which is 
one value used by the JDK to mean the default system class loader.  You 
can never assume the TCCL is non-null.  It's another good reason to use 
Class.forName() instead of classLoader.loadClass().

Thread.currentThread() will never be null.
