Hmmm, I assume this is used mainly to detect skin files' version?
Maybe we could create a kind of ResourceDescriptor file that would include two URLs, the real one and the container file's (the .jar URL for instance, but would be the same as the real URL most of the time). The getLastModified method of the ResourceDescriptor could then use that second URL for purpose of modification checks, theorically preventing the JVM from opening the JAR file.

I think I've found the problem - Trinidad calls URLConnection.getLastModified() in a number of places. If that's pointing at an URL from inside a JAR, this will implicitly open the JAR file, and not release the file until GC.
