IV46136: JDI STEPPING OUT DOES NOT WORK AS EXPECTED.

APAR status

• Closed as program error.

Error description

• Error Message: JDI stepping out does not work as expected.
  In the JDI test, the debuggee has methods1-5, method1 calls
  method2, method2 calls method3 etc.  The main method just calls
  method1. When the breakpoint set at method5 hits, the debugger
  request step out 5 times in a loop without disabling
  stepRequest. As a result, the execution point cannot be moved to
  each method sequentially(method4, method3, etc.)
  But with the Oracle SDK, it works fine. So the problem might be
  in our JDWP module.

  Stack Trace: N/A

Local fix

• Call StepRequest.disable() in the loop after step out event
  being triggered, then enable it again in the next loop.
  

Problem summary

• The problem is caused when step out request being used multiple
  times. JDWP module doesn't handle this scenario well.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR15
  7.0.0 SR6
  7.1.0
  .
  JDWP module has be enhanced to support this scenario mentioned
  above.
  

Temporary fix
