APAR status
Closed as program error.
Error description
Error Message: Segmentation error. . Stack Trace: One method that is known to hit this problem is org/apache/webbeans/container/InjectionResolver.implResolveByTyp e() .
Local fix
The problem can be avoided by passing -Xjit:disableLoopVersioner,disableLoopAliasRefiner,disableOpts={ loopSpecializer} for Java 8, or -Xjit:disableLoopVersioner,disableOpts={loopSpecializer} for Java 7.1, 7.0, or 6.1. These options are likely to degrade performance, but they can be limited to problematic methods.
Problem summary
The JIT compiler can hoist loads from memory out of a loop. Such a load may require a dynamic type check to establish that it is safe to perform. In certain cases the compiler could omit a necessary type check, producing output code that is not type safe. This problem is more likely to occur when running with -Xtune:virtualized.
Problem conclusion
The JIT compiler has been modified to generate the necessary type checks in these cases. . This APAR will be fixed in the following Java Releases: 8 SR5 FP17 (8.0.5.17) 7 SR10 FP30 (7.0.10.30) 6 R1 SR8 FP70 (6.1.8.70) 7 R1 SR4 FP30 (7.1.4.30) .
