jni.cc (_Jv_JNI_GetAnyFieldID): Throw ClassNotFoundException.

	* jni.cc (_Jv_JNI_GetAnyFieldID): Throw ClassNotFoundException.
	* java/lang/reflect/natMethod.cc (_Jv_GetTypesFromSignature):
	Rewrote to use _Jv_FindClassFromSignature.
	* verify.cc (resolve): throw NoClassDefFoundError.
	* link.cc (resolve_field): Throw NoClassDefFoundError.
	(find_field): Likewise.
	* prims.cc (_Jv_FindClassFromSignature): Removed recursion.
	Handle error cases.  Added 'endp' argument.
	* include/jvm.h (_Jv_FindClassFromSignature): Updated prototype.
