Rick Hillegas commented on DERBY-2905:
--------------------------------------
Hi Lily,
The following code snippet may help move this forward:
public static AutoloadedDriver makeAutoloadedDriver()
{
try {
return (AutoloadedDriver) Class.forName(
"org.apache.derby.jdbc.AutoloadedDriver40" ).newInstance();
}
catch (Throwable t) {}
return new AutoloadedDriver();
}
Hope that's useful.
Regards,
-Rick

> 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.
