Many applications, such as Xerces, do not set the use of caching to false before opening the URL connection to a JAR file, and that causes locking. Since Tomcat 5.0, a mechanism exists to prevent locking when accessing resources using the getResource method of the URLClassLoader. Tomcat has mechanisms to allow avoiding locking. Most locking issues will occur with JARs from /WEB-INF/lib, and are usually caused by access through URLs. I want to redeploy web applications, how do I prevent resources from getting locked? It is possible in Tomcat 6 and earlier, but not recommended. See the Tomcat Bug Report #13723 and Sun Bug Parade report #4776385 for the answer. That weird issue was observed many years ago and now is a history.
