Mike Matrigali commented on DERBY-5289:
---------------------------------------

I looked closer after mamta posted the results for 10.8.  I think the fix to 
DERBY-3870 may have fixed this issue.  Maybe knut can say whether it is 
appropriate to backport that whole change to 10.7 or not.  But my guess is that 
we only need the following change in 10.7 (and probably should 
backport it as far as possible as I think it could fix other issues for 
upgrade), should verify this one change fixes the problem in 10.7:

In DataDictionaryImpl.java knut made the change I was saying was a problem with 
the architecture.  You should not be deserializing the
SPS's during upgrade's attempt to drop/invalidate them:
    public List getAllSPSDescriptors()
        throws StandardException
    {
        TabInfoImpl                 ti = getNonCoreTI(SYSSTATEMENTS_CATALOG_NUM)
;

        List list = newSList();

        // DERBY-3870: The compiled plan may not be possible to deserialize
        // during upgrade. Skip the column that contains the compiled plan to
        // prevent deserialization errors when reading the rows. We don't care
        // about the value in that column, since this method is only called
        // when we want to drop or invalidate rows in SYSSTATEMENTS.
        FormatableBitSet cols = new FormatableBitSet(
                ti.getCatalogRowFactory().getHeapColumnCount());
        for (int i = 0; i < cols.size(); i++) {
            if (i + 1 == SYSSTATEMENTSRowFactory.SYSSTATEMENTS_CONSTANTSTATE) {
                cols.clear(i);
            } else {
                cols.set(i);
            }
        }

        getDescriptorViaHeap(
                        cols,
                        (ScanQualifier[][]) null,
                        ti,
                        (TupleDescriptor) null,
                        list);

        return list;

    }
