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.

.
This APAR will be fixed in the following Java Releases:
