    *                      scanning the server.xml resulting in    *

    ****************************************************************
    A null pointer exception (NPE) is encountered when installing
    server.xml features using installUtility if the features in the
    feature list are incompatible features for the server (i.e
    servlet-3.1 and servlet-4.0). The NPE Was the result of a
    previous bug that was fixed in fixpack 20.0.0.2, but the NPE was
    thrown while making an exception for the underlying server.xml
    resolution bug that this APAR is a fix for. The underlying
    problem is that the method we use to determine features from the
    server.xml gave us more features than we needed which caused
    issues with the resolver and gave it the impression that certain
    unnecessary features needed to be installed giving us the error
    of incompatible features.
    

Problem conclusion

  • The problem was fixed by filtering out the already installed
    features from server.xml before passing it to the resolver, this
    way no unnecessary features were requested by the resolver after
    resolution.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 20.0.0.4.  Please refer to the Recommended Updates page for
    delivery information:

Temporary fix

  • The user can manually install the incompatible server.xml
    features using installUtility install feature command
