Closed as program error.
Error description
Error Message: Segmentation fault in JIT compilation threads in function TR_BlockSplitter::synergisticDepthCalculator(...). Crash is only possible on 64-bit Big Endian POWER Linux and only when running Java 8. The problematic functionality is not enabled in versions of Java prior to Java 8 and users will not experience this issue when using those versions. . Stack Trace: N/A .
Local fix
Define and set the following environment variable for the Java process: TR_DisableBlockSplitterSynergy=1. This workaround may have a very small performance penalty in some cases.
Problem summary
The problem is caused by a defect in the C++ compiler used to build the JIT compiler.
Problem conclusion
The JIT compiler source code has been modified to work around the C++ compiler defect. . This APAR will be fixed in the following Java Releases: 8 SR2 FP10 (8.0.2.10) 7 SR9 FP30 (7.0.9.30) 6 R1 SR8 FP20 (6.1.8.20) 7 R1 SR3 FP30 (7.1.3.30) 6 SR16 FP20 (6.0.16.20) .
