I don't know what, if anything, would break if the AutoloadedDriver
unregistered itself. The embedded driver reference should be nulled out if the
engine is shut down. Is that not happening? What Derby code do you see running?

You are right. The AutoloadedDriver is loaded regardless of your JDBC level.
The javadoc should be corrected.
