Local fix

Problem summary

  • The problem is caused when a reference is explicitly enqueued
    before the Partial GC(PGC) and PGC comes across it during
    collection.
    

Problem conclusion

  • The JVM has been updated to safely ignore if the enqueued
    references were found in PGC internal references list.
    .
