Problem description
===================
The javadoc specification for the Instrumentation.setNativeMethodPrefix method at:
http://java.sun.com/javase/6/docs/api/java/lang/instrument/Instrumentation.html#setNativeMethodPrefix(java.lang.instrument.ClassFileTransformer
,%20java.lang.String)
states as follows:
  ---Excerpt-from-spec---
  Parameters:
    ...
    prefix - The prefix which has been applied to wrapped native methods.
  ---End-of-excerpt---

It would be fine to document that null value for prefix is acceptable but has no effect on the failure handling of native method resolution, i.e. equals to empty prefix.
