it turned out, that Tomcat suffers from a problem in Java's zip file
handling, which persists since years and most probably won't be fixed in the
next years. It also turned out, that the problem could be fixed by using
Ant's ZipFile class.
In the last days I inspected Tomcat's (4.1.30) sources for extracting WAR files. To be honest, I find them a real mess. The design decision for dealing with jar: and file: URL's seems to me to be severely broken, because in the end it depends on an underlying File anyways.
Attached you find a patch, which is *not* necessary to fix bug 26275. (Changes in ExtractWar would be sufficient.) However, I find it worth looking at, because you'll easily see that replacing URL's with File's reduces the code complexity quite much.
The attached patch is *not* ready for checkin, because I did not even test it. (That's why I omitted the [PATCH] in the subject.) I just wanted a first sign, whether it's worth to continue. If you don't like this work, let me know and I'll return with a smaller fix for 26275.
-1. I don't like your patch, sorry.
