I plan to try to get rid (as much as I can) of JAR URLs inside the Catalina (and Jasper) processing, because of the issues which (still, unfortunately :-( ) plague them in the JDK. I will use the fact that all the JAR URLs returned by the classloader are actually file based. I hope that way I'll be able to get rid of the file locking issues on Windows.
Similarly:
- the servlet context will be modified to return file URLs for JARs (but only for JARs) inside /WEB-INF/lib in response to getResource.
- /WEB-INF/classes/** and /WEB-INF/lib/** will be made non cacheable (as caching classes is useless by definition).
All that as part of an effort to reduce Tomcat memory footprint (to make it more suitable for large scale deployments), and reduce the amount of heavyweight objects used (such as file descriptors and threads, the latter having been taken care of).
For all those who are at J1, have a good J1 :)

Note: My deployer tweaks are almost done (without much testing), with the exception of moving the context descriptors to conf (thanks to Glenn for that idea, which will make the feature safer to use in TC 5).
Note 2: I intend to try to resurrect the "tester" suite when that is done.
Note 3: I plan to fix bug 4690 (finally). I have the algorithm on a piece of paper (as I didn't like the provided patch behavior).
Note 4: When all that is done, it'll be time for 5.0.3 IMO. As far as I am concerned, it will be mostly feature complete. Given the amount of stuff I still have to do, I'd give it a two weeks ETA.
