Lily Wei updated DERBY-2905:
----------------------------
Attachment: DERBY-2905_part2_2.diff
Thanks Rick. I am uploading patch DERBY_2905_part2_2.diff to change the
reloading the engine via Class.forName(…) resulted in the AutoloadedDriver
registered. This patch also provide the deregister attribute. The default
behavior for shutdown=true is to set deregister=true. AutoloadedDriver will not
be in DriverManager. If users set deregister=false, the AutoloadDriver will not
be deregister from DriverManager. The AutoloadTest create test cases like:
default shutdown behavior, deregister=true, deregister=false and also wrong
name of deregister attribute. The patch is ready for review.
Suites.all and derby passed before fixing the reload engine resulted in
AutoloadedDriver begin registered. I will run the tests again.
> Shutting down embedded Derby does not remove all code, the AutoloadDriver is
> left registered in the DriverManager.

> 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.
