	* java/lang/reflect/natMethod.cc (_Jv_CallAnyMethodA): Use
	_Jv_LookupInterfaceMethodIdx for calls to interfaces.
	* include/jvm.h (_Jv_CallAnyMethodA): Add new 	face' arg.

	* testsuite/libjava.lang/InvokeInterface.java: New file.
	* testsuite/libjava.lang/InvokeInterface.out: New file.

2004-04-14  Bryce McKinlay  <mckinlay@redhat.com>

	* class.c (get_interface_method_index): New function. Return
	dispatch index for interface method.
	(make_method_value): For interface methods, set index field to
	iface dispatch index, not DECL_VINDEX.
	* expr.c (build_invokeinterface): Use get_interface_method_index.
