    ****************************************************************
    A released connection was not actually removed from the shared
    pool in a particular scenario but its attributes were reset to
    Null. When the next getConnection request tried to read the
    attributes of these connections in the shared pool, the
    NullPointerException was thrown.
    

Problem conclusion

  • This fix removes the released connections properly from the
    shared pool and adds a Null check before reading the
    attributes from the connection.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.7 and the fix pack following 8.5.0.2.  Please
