Local fix

Problem summary

  • The problem is caused because a native library was loaded into
    the Java process via JNI, and native library contained symbols
    with very long names.  In the example submitted, the symbol
    names were autogenerated by C++.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    6.0.0 SR13
    .
    jextract has been updated to correctly process the long symbol
    names.
