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 19:33:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993651#comment-12993651

Kathey Marsden commented on DERBY-2905:
---------------------------------------

I am not kicking it over to you personally but rather suggesting we file a separate issue
and whomever is interested in fixing it can, but as you recall this issue, DERBY-2905 was
a regression introduced by your original Autoloader work. Several times your work has introduced
outright regressions including this one that you have left to others to fix.  In this case
of this regression, Lily has worked hard to fix the regression  and made her plans clear over
the course of development.   I am sure it would have been helpful to communicate more about
potential conflicts during that process.

> 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.
