This comes from the underlying Felix library and when I last pointed it out Micha said that it still wasn’t fixed even on the latest version of Felix. Based on what Felix is doing (adding custom URLs to a URLClassloader) I’m not sure Felix will be able to change that code until the JDK changes to allow what they need. So Lucee is stuck with this warning until Felix changes.
