Web container needs to call javax.faces.FactoryFinder.releaseFactories() at undeployment ---------------------------------------------------------------------------------------- Key: JBAS-2065 URL: http://jira.jboss.com/jira/browse/JBAS-2065 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Tomcat) service Affects Versions: JBossAS-4.0.3RC1 Reporter: Stan Silvert Assigned To: Stan Silvert Priority: Minor Now that we have JSF integrated as part of the Web Container, there will only be one instance of javax.faces.FactoryFinder per JVM. FactoryFinder provides a method called releaseFactories() which is intended to be used in situations where JSF is integrated as ours now is. It dereferences the various per-app factories used. These factories are stored in a Map that is keyed by the web app's context classloader. See http://java.sun.com/j2ee/javaserverfaces/1.1/docs/api/javax/faces/Factory... Though I have not verified it, not calling releaseFactories() should cause a memory leak any time a JSF application is undeployed or redeployed. Incidentally, this leak probably occurs 4.0.2 when two JSF applications use JBossWebLoader=true. To fix this according to the JSF spec, we should call FactoryFinder.releaseFactories() any time we undeploy a web application. Of course, we would also need to make sure that the FactoryFinder class exists in case JSF is removed from JBoss AS.
