Title Body

I have just started using Google Guice with my Tomcat webapp, and have noticed the following in the catalina.out file whenever the WAR file is undeployed: May 16, 2011 5:37:24 PM org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [/app] May 16, 2011 5:37:24 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads SEVERE: A web application appears to have started a thread named [com.google.inject.internal.util.$Finalizer] but has failed to stop it. This is very likely to create a memory leak. May 16, 2011 5:37:24 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap SEVERE: A web application created a ThreadLocal with key of type [null] (value [com.google.inject.internal.InjectorImpl$1@10ace8d]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@7e9bed]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed. Does anyone know what causes this, or how I can stop it from happening? I have only followed the instructions from here http://code.google.com/docreader/#p=google-guice&s=google-guice&t=ServletModule ... and haven't done anything fancy with it yet. I just have 2 servlets and a filter. Thanks!
