that this is a PermGen memory error, which is connected with
classloading, not heap memory usage. This commonly happens
when redeploying a web application without a clean restart
of the app server. I don’t fully understand this type of
error, but you might like to try cleanly restarting your app
server (if you’re using one) or increasing the permgen space
using a command-line switch to the JVM (sorry, can’t
remember what the syntax is!)</span></p>

Thanks for the feedback. Actually there is known issues in Geotk
regarding undeployment: some threads are not killed and some <tt>java.lang.ThreadLocal</tt>
variables are not cleared, which prevent the JVM to unload every
Geotk classes before to reload them when redeploying.<br>
<br>
An attempt to mitigate the problem has been provided with the <a
href="http://www.geotoolkit.org/apidocs/org/geotoolkit/lang/Setup.html#shutdown%28%29"><tt>Setup.shutdown()</tt></a>
static method, which can be invoked when you know that your
application is about to be undeployed (if possible). However this
does not solve all issues. We are investigating usage of JSR-330 and
OSGi (now that Oracle confirmed that JDK-8 will be compatible with
OSGi) as a better fix (but we will not force user to use OSGi).<br>
<br>
In the maintime the workaround proposed by Jon still the most
reliable approach.<br>
