Usage

From source file:org.geoserver.GeoserverInitStartupListener.java

/**
 * This method tries hard to stop all threads and remove all references to classes in GeoServer
 * so that we can avoid permgen leaks on application undeploy.
 * What happes is that, if any JDK class references to one of the classes loaded by the
 * webapp classloader, then the classloader cannot be collected and neither can all the
 * classes loaded by it (since each class keeps a back reference to the classloader that
 * loaded it). The same happens for any residual thread launched by the web app.
