It would be nice it that were added.

Client SUR changes some metadata (in metadata_net.properties) and
relies on DERBY-1176 for correct operation under upgrade for some
metadata queries, cf. the DERBY-775 write-up.

As I was working with DERBY-775, it struck me that the JCC client
might get problems when metadata_net.properties is updated to reflect
Derby client capabilities not necessarily present in the JCC driver.
Should there perhaps be different code paths for the two drivers(JCC,
DerbyNetClient) wrt SYSIBM metadata? Not my itch, but...
