Pity my Derby internals proposal was rejected by Apachecon Europe :-)

There are actually four committers (I'm one) and five other developers
who are employed by IBM and work on the database internals code, and
there are 219 people subscribed to Derby's developer list, and posts
from 228 authors this year.
So it's not a case of 'so few other developers', some of those
developers are contributing patches for bugs and features and are
progressing towards being committers.

Derby seems to have a reasonable number of people subscribed to its
developer list compared to other Apache projects, from looking at Ken's
mailing list page, I think Derby is around 25th based upon number of
subscribers out of all active Apache developer lists, and most above it
are in the 240-300 range, so Derby is in line there. Derby is possibly
the highest developer subscriber count for an incubator project. iBatis
is at 54 subscribers and nutch at 140, both of which I think have been
approved to graduate.

The developers employed by IBM know that and practice that all Derby
discussion takes place on the developer list, we have been helping out
anyone on the list who asks questions about internals etc, several IBM
folks have spent time writing up internal information and posting it to
the list, we've presented at conferences.

I think the activity on the list shows that an active multi-participant
community has been built.

I think it goes to Ken's question of how much more can the incubator
project benefit Derby.
