The timer is used in order to close all SQL connections to the EPSG database when it has not been used for a while (connections are automatically opened again when a new request is performed). Connections are closed after some delay in order to release more resources for user's application.

I started the thread in http://sourceforge.net/mailarchive/forum.php?thread_id=9952584&forum_id=12232

Some more informations, that might help

I'm using Geotools 2.2-M0
The applet and all used geotools-libraries are signed with a certificate
I'm opening Shapefiles and rendering with ShapefileRenderer
On reloading the page, the error occurs, not everytime, but in most cases
Some days ago it prevented me from refreshing the page with a new applet (I uploaded a new applet-version, wanted to test it and the old one still showed up)
The error does not occur when loading the page for the first time
Except from the one time, where it prevented me from loading a new version, this error does not affect the functionality of my applet in any way

Changed the priority to "minor", since it doesn't prevent the AuthorityFactory to work. It probably prevent the resources to be released however. This bug still need to be fixed in order to avoid wasting memory.

The way DeferredAuthorityFactory (renamed ThreadedAuthorityFactory after Refractions work) disposes the resources have completly changed in geotidy. We now relies much more extensively on the java.util.concurrent package, which is new to Java 5. I believe the new framework to be more robust than the old one, but we need still need more experiments to be sure.
