Lily Wei commented on DERBY-2905:
---------------------------------

Thanks, Rick. The patch is check-in svn 1068842. If the reloading the engine via Class.forName(...).newInstance
resulted in AutoloadedDriver registered does not load the desire AutoloadedDriver, please
feel free to change the code. Before resync the latest change, Suites.all and derbyall passed.
Hope this help, thanks!

> After a shutdown of the embedded driver the AutoloadDriver is not unregistered from DriverManager.
However it does not support any future loading of connections so it has no value in remaining
registered. Since the DriverManager class will remain forever, this means the Derby code will
remain forever in the JVM, even if Derby was loaded by a separate class loader.
> Regression from 10.1 since before the AutoloadedDriver the internal driver did unregister
itself from the DriverManager on a shutdown.
