Error description

  • Error Message: ASSERT:MarkingScheme.cpp:1673

    ReferenceQueue.remove() are used on objects.
    .
    Stack Trace: N/A
    .
    

Local fix

  • Move to a non-concurrent GC policy, such as optthruput by using
    -Xgcpolicy:optthruput
    

Problem summary

  • The problem occurs as a result of the application calling
    Reference.enqueue() and ReferenceQueue.remove() on a reference
    object after a Concurrent GC phase has begun, but before the GC
    completes.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR6
    6.0.1 SR7
    .
    The JVM has been updated to take into account the use of
    Reference.enqueue() and ReferenceQueue.remove() during the
    Concurrent GC phase
    

Temporary fix
