org.eclipse.persistence.internal.libraries.asm.CodeVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. This opcodeis either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

            String methodDesc = Type.getMethodDescriptor(method);
            String[] exceptionsDesc = new String[] { Type.getType(ObjectStreamException.class).getInternalName() };


            CodeVisitor mv = cw.visitMethod(ACC_PROTECTED, method.getName(), methodDesc, exceptionsDesc, null);
            mv.visitVarInsn(ALOAD, 0);
            mv.visitMethodInsn(INVOKESPECIAL, Type.getInternalName(getParentClass()), method.getName(), methodDesc);
            mv.visitInsn(ARETURN);
            mv.visitMaxs(0, 0);
