> I get the following warnings at the end of Maven build:
> {code}
> Cleaning up unclosed ZipFile for archive C:\...foo-0.2.0-SNAPSHOT.zip
> {code}
> These warnings originate from assembly plugin, but in fact they're caused by the fact
that plexus resource abstraction opens up a ZipFile from commons-compress, but never closes
it. Commons-compress then force-closes all such objects in finalize, emitting a warning.
> I created a synthetic capture of the allocation stack in maven assembly, it's here:
> {code}
