Not assert what you're seeing is the same as what I was seeing, but I
observed some evidence of jetty retaining file descriptors when the
hot-deploy feature was utilized:

  http://dev.eclipse.org/mhonarc/lists/jetty-dev/msg02777.html

In that, I was fixated on disk space consumption, but the disk space
was consumed as jetty was retaining references to deleted files.

That resulted in me opening this bug:

  https://github.com/eclipse/jetty.project/issues/867

And the resulting assertion is that it's not a bug, but a known
behavior of Java that you can tune away.

Anyway, this may not be at all related to what you're seeing, but
wanted to provide a heads-up.
