APAR status
Closed as program error.
Error description
Error Message: An Illegal Instruction Exception is raised when executing a compiled method which does UTF16 Encoding. . Stack Trace: N/A . This problem only affects z Systems hardware generations which are older than z196.
Local fix
This issue can be worked around by using the JVM option, -Xjit:disableZGryphon Note that this can affect performance. Alternatively, the problematic method can be excluded from compilation using the following JVM option, -Xjit:exclude={complete_method_description} Note that this can affect performance.
Problem summary
This problem is caused by the JIT compiler selecting an instruction on pre-z196 hardware which is only supported on z196 and later hardware.
Problem conclusion
The JIT compiler has been updated to only generate the problematic instruction on z196 or later hardware. . This APAR will be fixed in the following Java Releases: 8 SR1 FP10 (8.0.1.10) .
