      Description

        Mostly this is harmless, because we have workarounds in the code like the following:

            case Bytecodes::_arraylength:
              // The return type of arraylength is wrong in the bytecodes table (T_VOID).
              stack->pop(1);
              stack->push(bci, T_INT);

        however, I did get a crash in compiler/c1/CanonicalizeArrayLength.java when running with -XX:+DeoptimizeALot -XX:+VerifyStack because of this problem.
