Error description

  • A very rare problem leading to abnormal termination of the JVM
    caused by an object being garbage collected before finalization.
    
    Stack Trace:
    
    The failing method is likely to be one of the *_Unsafe_get*
    methods, although this may not be displayed in the initial
    failure report and so may take further investigation to find.
    

Local fix
