IJ14197: CRASH DURING JIT COMPILATION

APAR status

• Closed as program error.

Error description

• Error Message: While running in debug mode the JVM crashes and,
  depending on system configuration, generates system core,
  javacore etc. The javacore indicates that the crash occurred in
  libj9jit29.so and will include a "Compiling method:" entry that
  specifies the method that the JIT was compiling when the crash
  occurred.
  This problem can only happen in Java 8 SR5.
  .
  Stack Trace: Corefile analysis will likely indicate that the
  crash happened in TR_OSRLiveRangeAnalysis::buildOSRLiveRangeInfo
  .
  

Local fix

• The problem can be avoided by either:
  not running with debug, or
  using the command line option -Xjit:mimicInterpreterFrameshape
  

Problem summary

• JIT analysis for OSR depends on correctness of the bytecode
  index information attached to each node. Some optimisations can
  create nodes with an incorrect bytecode index, which for the
  nodes in question would not normally be a problem except for the
  case where the OSR analysis runs after they were created.
  

Problem conclusion

• The OSR analysis steps have been moved earlier in the
  optimisation strategy so that they precede the steps which can
  create nodes with incorrect bytecode indices.
