APAR status

  • Closed as program error.

Error description

  • Error Message: Unhandled exceptionType=Segmentation error
    vmState=0x00050dff
    .
    Stack Trace:
    .
    This crash could also occur while compiling other methods that
    call StringCoding.decode(), directly or indirectly.
    

Local fix

  • -Xjit:disableConverterReducer
    

Problem summary

  • As an optimization, the JIT compiler reduces invocations of
    particular character conversion methods to intrinsics. In
    certain circumstances, this reduction could produce invalid
    code, which would cause a crash later in the compilation.
    

Problem conclusion

  • The JIT compiler has been modified so that these circumstances
    no longer cause it to produce invalid code when optimizing
    character conversions.
    .
    This APAR will be fixed in the following Java Releases:
       7 R1 SR3       (7.1.3.0)
    .
