  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.
