Subject [jira] Commented: (DERBY-2905) Shutting down embedded Derby does not remove all code, the AutoloadDriver is left registered in the DriverManager.
Date Fri, 11 Feb 2011 19:54:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993663#comment-12993663

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

+1 on communicating more in turn of conflicts and potential fix. I will be more than happy
to keep working on resolving getParentLogger issue for AutoloadedDriver. I will definitely
appreciate Rick's suggestion for how to proceed.
As far as I can see, we need to create AutoloadedDriver40 in AutoloadedDriver.registerDriverModule.
Something like this:
           if (_autoloadedDriver == null) {
                //Support JDBC 4 or higher (DERBY-2905)
                if (HAVE_DRIVER && HAVE_SQLXML) {
                    AutoloadedDriver40.reloadAutoloadedDriver40();
                }
However, I am having compiler error on the line "AutoloadedDriver40.reloadAutoloadedDriver40
on reflect, invoke etc.

> 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.
