APAR status
Closed as program error.
Error description
Error Message: A SIGSEGV/GPF is raised by the JIT compiler. The problem is known to be hit when compiling java/awt/image/BufferedImage.<init>(III)V . Stack Trace: Multiple stack traces are possible. One known stack trace is: TR_UseDefInfo::findTrivialSymbolsToExclude TR_UseDefInfo::AuxiliaryData TR_UseDefInfo::prepareUseDefInfo TR_UseDefInfo::TR_UseDefInfo OMR::Optimizer::performOptimization . The problem can only be hit on a SIMD capable machine with vector instructions.
Local fix
The problem can be avoided using the following command line option: -Xjit:disableAutoSIMD Note, use of this option may have a performance impact. It is likely to be negligible, but certain workloads that significantly benefit from vectorization may notice an impact.
Problem summary
The JIT compiler may try and convert loops in order to make use of SIMD vector instructions to accelerate performance. If a loop is suitable for this optimization, and has a statement like a<OSB>i<CSB> = i; where i is a loop counter, then the optimization may not properly set internal JIT data structures in the compiler's IL. A subsequent optimization will then crash when encountering the problematic data structure(s).
Problem conclusion
This problem has been addressed by https://github.com/eclipse/openj9/pull/5200 . This APAR will be fixed in the following Java Releases: 8 SR5 FP35 (8.0.5.35) .
