  Note this can affect all platforms.
  

Local fix

• -Xjit:disableNextGenHCR. Note however that this will cause
  throughput performance drop of around 3% depending on the actual
  application
  

Problem summary

• The problem is caused when class redefinition happens and
  execution of compiled code transit to interpreter at bytecode
  for invoking a function call. The compiled code would pass
  incorrect arguments to the interpreter due to wrong book

Problem conclusion

• The JIT compiler has been updated to pass correct arguments when
  transit to interpreter at invoke bytecode.
