APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    The values of floating point parameters may not be passed
    correctly to native code across JNI calls.  This problem is seen
    on 31-bit z/OS JVMs with Java invoking non-XPLINK native code.
    

Local fix

  • This issue can be worked around using the
    -Xjit:disableDirectToJNI option.  Note however that this option
    will cause additional performance overhead across JNI calls.
    

Problem summary

  • The problem is caused by the JIT compiler failing to store
    floating point parameters into the argument list on the native
    stack.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR7
    7.0.0 SR6
    .
    The JIT compiler has been updated to correctly pass the floating
    point parameters.
    

Temporary fix
