Error description

  • Error Message: An illegal instruction exception is raised in an
    AOT-compiled method when a Java program is being run on Linux on
    System z with -Xshareclasses enabled.
    .
    Stack Trace: N/A
    .
    

Local fix

  • This problem can be avoided by disabling class sharing, or by
    setting the JVM option -Xaot:exclude={full method
    name},loadExclude={full method name} for the method that is
    causing the issue. Disabling class sharing may cause some
    performance degradation.
    

Problem summary

  • The problem is caused by missing relocations on some method
    calls in an AOT-compiled method on Linux.
    

Problem conclusion

  • This APAR will be fixed in the following Java Releases:
       7 R1 SR1       (7.1.1.0)
       7    SR7       (7.0.7.0)
       6 R1 SR8       (6.1.8.0)
       6    SR16      (6.0.16.0)
    .
    The JIT compiler has been updated to generate the relocations
    correctly.
