Fix Version/s: 2.8
- java version "1.7.0_80" ,Java(TM) SE Runtime Environment (build 1.7.0_80-b15), Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

NPE when logging in Java EE/OSGi environment.
In some cases the ClassLoader ( https://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getClassLoader() ) will be null for a Class.
With the changes introduced in
https://issues.apache.org/jira/browse/LOG4J2-1457 logging with %xEx can cause a NullPointerExeception when trying to resolve the stack.
Since it's not a common occurrence in most environments I suggest the ThrowableProxy swallow the NPE in the same way it swallows SecurityExeception and other classloading exceptions to avoid extra branching for all environments.
