APAR status
Closed as program error.
Error description
Error Message: A segmentation error occurs during compilation when the JVM is in the start-up phase running in an emulated 31bit zLinux OS. . Stack Trace: N/A . This only affects the JVM when running in an emulated 31 bit zLinux OS environment.
Local fix
This issue can only be worked around by disabling the JIT compiler with the -Xint option.
Problem summary
The problem is caused by the JIT compiler relying on the Linux uname command to determine if the hardware is 64bit.
Problem conclusion
The JVM only supports 64bit hardware therefore the query was invalid and the JIT compiler was modified to remove the query to prevent the segmentation error in this circumstance. . This APAR will be fixed in the following Java Releases: 7 R1 SR3 FP10 (7.1.3.10) 6 SR16 FP7 (6.0.16.7) 7 SR9 FP 10 (7.0.9.10) 6 R1 SR8 FP7 (6.1.8.7) 8 SR1 FP10 (8.0.1.10) .
