This is puzzling. I did a very simple experiment;
- connect with ij with 10.1 jars in my classpath and created a db
   ij> connect 'jdbc:derby:tstdb;create=true';
- connect with upgrade with 10.5 jars in my classpath
   ij> connect 'jdbc:derby:tstdb;upgrade=true';
- with my 10.5 jars in the classpath, issue the query you mentioned:
   ij> values syscs_util.syscs_get_database_property( 'DataDictionaryVersion' );
   ------------------------------------------------ (etc...)

Perhaps you won't mind doing the same experiment to verify it works
for you this way?

Then, well, perhaps there was a simple mistake in your upgrade step?
I assume you made a copy of your db before the upgrade; so try it
again, (with a fresh copy), this time catching extra info in your
derby.log. You can do this by creating a derby.properties file in the
dir where you start derby, and adding the following to it:
This should catch all activity and give more details about any
possible warnings.

Apart from this, I can only theorize - perhaps a simple typo? Or
perhaps your 'upgrade=true' connection was not the first connection to
the db with 10.5 jars?
Once you're connected via soft upgrade, you cannot simply do a hard
upgrade; but you'd get an error if this is what happened...("URL
Attribute [update=true] Attribute is unknown to Derby").
