The JCK invokeinterface02001 test (see source below) discovers
that inappropriate AbstractMethodError exception is thrown under
the interface nonpublic method invocation for 1.2b3C JVM on WinNT.
The jvm spec (6.4 The Java Virtual Machine Instruction Set) demands
the rising of the IllegalAccessError in this case.
