Hi Mark, Thanks for the info. But I am afraid the custom loader directly extends URLClassLoader. Actually my application is a generic web app which can be deployed in any ApplciationServer like tomcat, JBoss, etc. So I don't have any tomcat specific implementations.

But if I > try to get " my/secret/password", it returns NULL. This works for me with both 9.0.x and 8.0.x. Your previous posts mentioned a custom class loader. If the web application class loader is not the thread context class loader then the resource will not be visible. Is that custom class loader a child of the web application class loader? If so, a fix for the next release should be fairly simple.
