IV72331: CRASH WITH VMSTATE=0X00000000

APAR status

• Closed as program error.

Error description

• Error Message: A variety of errors are possible, but the most
  likely outcome is:Unhandled exceptionType=Segmentation error
  vmState=0x00000000
  .
  Stack Trace: N/A
  .
  Most likely to occur when an agent is attached to do hot-swap of
  classes, or in scenarios using a debugger (like Eclipse, for
  example) that uses JVMTI to step through Java code and set
  breakpoints.
  

Local fix

• -Xjit:disableOSRSharedSlots
  

Problem summary

• The JIT compiler could generate incorrect code to transition to
  the interpreter for certain methods that manipulate values of
  type long or double in certain ways.
  

Problem conclusion

• The JIT compiler has been modified so it correctly computes the
  operand stack usage for values of type long or double when
  transitioning to the interpreter.
  .
  This APAR will be fixed in the following Java Releases:
