    Description

      JDK-8072498 added support for processing of off-heap weak references, by adding parallelization support to WeakProcessor. ParallelGC is not yet using this, because it doesn't use the WorkGang parallelization infrastructure, (on which the WeakProcessor parallelization is based) but instead uses its own parallel worker infrastructure. Either extend WeakProcessor to support the ParallelGC mechanism, or fix JDK-8204951 and hook up ParallelGC.
