APAR status
Closed as program error.
Error description
Error Message: A SIGFPE or an ABEND is raised in the Java Just-In-Time compiler module (libj9jit) due to an attempt to divide by zero. . Stack Trace: TR_BranchProfileInfoManager::getBranchCounters TR_CFG::getBranchCounters TR_CFG::getInterpreterProfilerBranchCountersOnDoubleton TR_CFG::setBlockFrequenciesBasedOnInterpreterProfiler TR_CFG::propagateFrequencyInfoFromExternalProfiler TR_IProfiler::setBlockAndEdgeFrequencies TR_CFG::setFrequencies TR_Inliner::perform TR_OptimizerImpl::performOptimization TR_OptimizerImpl::optimize TR_Compilation::performOptimizations TR_Compilation::compile .
Local fix
This issue can be avoided by preventing the compilation of the failing method with the -Xjit:exclude={...} option.
Problem summary
The problem is caused by the JIT compiler incorrectly attempting to compute the hotness ratio of code paths exiting a cold branch.
Problem conclusion
The JIT compiler has been updated to prevent the division by zero. . This APAR will be fixed in the following Java Releases: 6 R1 SR8 FP3 (6.1.8.3) 7 SR8 FP10 (7.0.8.10) 7 R1 SR2 FP10 (7.1.2.10) .
