The VM should throw an exception if JVM_GetCallerClass is called by any 
method other than Reflection.getCallerClass().  It's a good idea to add 
such test case.

I considered detecting if this method is called by a system class (loaded by null loader) and throw an error.  I decided to minimize the compatibility risk in case if there is any existing code added to the bootclasspath depending on this private API.
