Re: [jboss-dev] Multiple classLoaders for a single WAR file on Tomcat

This is probably a question for Remy: Why Tomcat creates multiple ClassLoaders for every deployment? Is this by design or this is a leak? For a single WAR, I'm seeing 4 classLoaders deployed just wasting PermGeneration memory. For example, I deployed a single WAR, and I've got this Servlet loaded by 4 distinct classLoaders. and this is a standard behavior I have seen on Tomcat for a long time already. org.jboss.on.plugins.servlet.test.Counter: - java.net.URLClassLoader@10891966 - org.jboss.web.tomcat.tc5.WebAppClassLoader@18775238 - java.net.URLClassLoader@22498184 - org.jboss.web.tomcat.tc5.WebAppClassLoader@8238932 Also... if you use any other profiler (besides the ClassLoader analysis I've written on JBossProfiler) you could be foolished by them as those classes won't have any instances... Just the classDef loaded on the heap.
