@Override
  public boolean isRegionInvalid() {
    return regionInvalid;
  }
Implementation of a local scoped-region. Note that this class has a different meaning starting
with 3.0. In previous versions, a LocalRegion was the representation of a region in the VM.
Starting with 3.0, a LocalRegion is a non-distributed region. The subclass DistributedRegion adds
distribution behavior.
