    N/A
    
    ======================================
    
    Under rare circumstances a variable may be initialized every
    time around a loop instead of once at the beginning. This could
    manifest as unexpected exceptions or incorrect output.
    

Local fix

  • Use -Xint to avoid using the JIT, or use
    -Xjit:disableEscapeAnalysis to disable the specific optimisation
    causing to the problem.
