      Description

        The ParallelObjectIterator should have virtual destructor, since implementations of CollectedHeap::parallel_object_iterator() returns the base type, which is later passed to the delete operator.

        Today both G1 and Shenandoah leaks memory here. I noticed this bug when when implementing ZCollectedHeap::parallel_object_iterator(). Bug was introduced in JDK-8215624.
