Summary: Static reference from javax.security.auth.Policy.contextClassLoader prevents an undeployed Web application from being garbage collected Product: Tomcat 7 Version: 7.0.0 Platform: Sun OS/Version: Solaris Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: dev@tomcat.apache.org ReportedBy: arjencornelis.kni...@getronics.com Overview The class javax.security.auth.Policy has a static member contextClassLoader that can refer to the WebappClassLoader of an application. If that happens, the web application cannot be garbage collected after undeploy. Steps to reproduce Create a web application that uses Axis 1 as SOAP server. Deploy the web application in Tomcat. Make a SOAP call to the webapplication. Undeploy the web application. Wait an hour. Make a memory dump using jmap, and inspect the memory using jhat. Actual results The WebappClassLoader for the web application is still present. Its "reference chains from rootset" shows a reference like this: System Class Reference : --> class javax.security.auth.Policy (84 bytes) (static field contextClassLoader:) --> org.apache.catalina.loader.webappclassloa...@0xeb52ba60 (165 bytes) Expected results There is no WebappClassLoader for this web application anymore.
