        Description

        In method StubGenerator::generate_copy_longs(...) there are statements of the form

         __ align(6)

        The intention presumably being to align the code buffer on a 64 byte boundary, however the implementation of align(...) does

        void MacroAssembler::align(int modulus) {
          while (offset() % modulus != 0) nop();
        }
