IV78207: JAVA SEGMENTATION ERROR IN ESCAPE ANALYSIS

APAR status

• Closed as program error.

Error description

• Error Message: The JIT compiler crashes during escape analysis.
  .
  Stack Trace:
  .
  

Local fix

• The problem can be avoided using the option
  -Xjit:disableEscapeAnalysis. Note this might have a slight
  impact on performance, but in most cases it will be less than
  1%.
  

Problem summary

• Escape analysis, an optimization that determines whether an
  object may escape
        a given scope, could under certain circumstances treat an
  operation involving
        a statically unknown class as though the class were
  statically known.
  

Problem conclusion

• The JIT compiler has been modified so that escape analysis will
  correctly
        determine in these cases that the class is unknown.
