Subject: 2002-07-04  Tom Tromey  <tromey@redhat.com>             Jeff Sturm 
 <jsturm@one-point.com>

	Fix for PR libgcj/7060:
	* java/lang/Class.h (_getMethod): Renamed from getMethod.
	* java/lang/natClass.cc (_getMethod): Renamed from getMethod.
	Recurse into superinterfaces.  Don't throw NoSuchMethodException.
	* java/lang/Class.java (getMethod): New Java implementation;
	complies with spec.
	(_getMethod): New native method.
