Thanks, Dag and Øystein, for your comments! I have uploaded a new patch with
the modifications you suggested. Since I had problems deciding which elegant
rewrite of the if statement I should choose, I chose a hybrid and added
comments to clarify.
The upgrade test still runs cleanly, and my manual test of the client/metadata
issue passes too. Have started a derbyall run now, just in case. If there are
no more comments, I will commit the patch tomorrow.

> When upgrading a database created with Derby 10.1 to 10.2, the SPSs in
> the SYSIBM schema are not updated. SYSIBM.METADATA was modified in
> DERBY-965, but it still has the old behaviour after the upgrade (both soft and
> hard).
> How to reproduce:
> 1. Create a database with 10.1.
> soft upgrade:
> 2. Start 10.2 network server.
> 3. Connect to the 10.1 database with the 10.2 client driver and
> invoke DatabaseMetaData.supportsResultSetConcurrency(
> ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY). Return
> value: FALSE.
> hard upgrade:
> 4. Restart 10.2 network server.
> 5. Connect to the database with "upgrade=true" added to the
> URL. DatabaseMetaData.supportsResultSetConcurrency(
> Restart.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY) returns
> FALSE.
> observe correct behaviour:
> 6. Delete the database and recreate it with 10.2.
> 7. Start 10.2 network server.
> 8. Connect to the database with the client driver and invoke
> DatabaseMetaData.supportsResultSetConcurrency(
> Restart.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY). Return
> value: TRUE.
> Proposed solution for hard upgrade: drop and recreate SPSs.
> Proposed solution for soft upgrade: read SYSIBM.METADATA from
> metadata_net.properties.
