Problem Description
-------------------
sun.reflect.Reflection.getCallerClass(int) has changed its behaviour such
that a different Class is now returned for a given integer. It looks like
getCallerClass is now calling another method on Reflection, which has changed
the call stack. Attached is a test class that exhibits the problem.
For jdk7u21, its output is:
sun.reflect.Reflection
sunreflect.ReflectionCaller$Inner2
sunreflect.ReflectionCaller$Inner1
sunreflect.ReflectionCaller
But for 7u25, its output is:
sun.reflect.Reflection
sun.reflect.Reflection
sunreflect.ReflectionCaller$Inner2
sunreflect.ReflectionCaller$Inner1
