APAR status
Closed as program error.
Error description
Error Message: A segmentation error is produced by the JIT compiler when trying to invoke a JCL native method. . Stack Trace: N/A . The value in the register which causes the segmentation error will look like CPU instructions.
Local fix
If the problem is specific to a method, it can be worked around by excluding the compilation of that method using -Xjit:exclude={package/class.method(signature)} Note that this may impact performance.
Problem summary
This problem is caused by a very small timing window within the JIT compiler where it is possible for a JIT compiler internal data structure to get updated in between uses of that data structure. The result is the wrong value is passed to the JIT compiler helper function used to invoke JCL native methods.
Problem conclusion
The JIT compiler has been updated to prevent the incorrect value from being passed to the helper function used to invoke JCL native methods. . This APAR will be fixed in the following Java Releases: 6 R1 SR8 FP15 (6.1.8.15) 6 SR16 FP15 (6.0.16.15) 8 SR2 (8.0.2.0) 7 SR9 FP20 (7.0.9.20) 7 R1 SR3 FP20 (7.1.3.20) .
