I'm not reproducing a problem. At the very
minimum, in FileInputStream.finalize(), fd.handle always
seems to be -1 now, whereas it used to be still set
a lot before. Admittedly I'm not using Tomcat,
antiJarLocking or no antiJarLocking.
Is it possible that Matthias gave you a snapshot before
the fix landed?

That's right. And also these files are closed by first GC. But the files listed in my
last post are really opened repeatedly and I see more and more of them with every
open browser session. The .js files seem to be cached in the browser so the open
files are not duplicated every time. But by doing a browser refresh I can increase
the number of open files by about 30.
