Well. Derby is *not* an end-user product, so the Derby users are
themselves developers.

I see your concerns. But I have done this maneouver several times in my
career with various open source products (the list is very long, but I
started with some platform problems with emacs on Sun386i in the late
80s), and the build process wasn't always smooth (I even once had to
edit a files in SunOS /usr/include to make gcc compile). Don't
underestimate the Derby users.

The option will always be there for the most eager users, since JDBC4 is
always in the trunk, and even if we remove JDBC4, we can't rollback svn
and undo what we've done.
