Shenandoah: Assertion failure in nightly test

    Details

    • Subcomponent:
      gc

      Description

      Following assertion failed on 2019-08-07 nightly kitchensink-jcstress test. The cause is actually due to the bad assertion itself, as _index == _size is possible when array is full. Ironically, the same assertions are handled correctly elsewhere.

              # Internal Error (/home/jenkins/workspace/nightly/shenandoah-jdk/src/hotspot/share/gc/shenandoah/shenandoahNMethod.cpp:354), pid=123793, tid=123808
              # assert(_index >= 0 && _index < _size) failed: Sanity
