Error description
Error Message: Segmentation faults in jit dll with a vmState and a Method_being_compiled. The vmState and the Method_being_compiled can vary in different failures. An example is as follows: Type=Segmentation error vmState=0x000531ff Module=W:\builds\bld_304222\sdk\wi3280\jre\bin\default\j9jit28.d ll Method_being_compiled=com/ibm/jtc/svt/streams/TestStreamOperatio ns.testStreamsSum()V . Stack Trace: TR_J9VM::getClassClassPointer verifyFieldAccess TR_J9VMBase::transformIndirectLoadChainImpl TR_J9VMBase::transformIndirectLoadChain ... .
Local fix
The problem can be worked around using the -Xjit:disableKnownObjectTable option. Using this option may reduce performance.
Problem summary
When compiling a method, the JIT would load a field of an object that is known to stay unchanged during the program. In certain circumstances, the reference to the object can be unresolved in the constant pool, leading to a crash in the JIT. This issue affects all platforms.
Problem conclusion
The JIT compiler has been fixed to avoid the problem by checking whether the reference to the object is resolved. . This APAR will be fixed in the following Java Releases: 7 R1 SR4 (7.1.4.0) 8 SR3 FP21 (8.0.3.21) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
