It seems to be a bug in plexus-archiver.
I see only one solution, look at plexus-archiver code and fix it to close files
that aren't closed.

Hi,
We ran into a problem with a large maven2 build. In the last stages of
the build (creating the war) an exception is thrown saying that there
are too many open files. We're using continuum 1.0.3 on a debian
(stable) server. We've already upped the system/process file handle limits.
The last part of the maven output:
