Description

From the patch:

// post process for the fetchGroup: if there is a
// fetchgroup field, then go to the FetchConfiguration
// to get the required fetch fields.
if (fgs != null) {
if (fields == null)
fields = new BitSet(fmds.length);
BitSet fgFields = fetch.requiresFetch(fgs, fmds);
// merge the fetchgroup required fields to the original
// fields only the fields are not already loaded and
// are not in the original fields.
for (int j = 0; j < fgFields.length(); j++)

{ if (fgFields.get(j) && !fields.get(j) && !_loaded.get(j)) fields.set(j); }

}

That code introduces an NPE if fetch is null. This is legal; see PNonTransState:108, for example.
