[MVT] java.lang.Class::isAssignableFrom() C2 intrinsic does not support value types

    XMLWordPrintable

    Details

      Description

      The C2 intrinsic for java.lang.Class::isAssignableFrom does not work properly with value types (it returns false for __Value.class.isAssignableFrom(vt) when vt is a value type class).

      Once this is fixed, we should revert the -XX:DisableIntrinsic=_isAssignableFrom flag:
