Is this bug fixed? I had the problem for a long time and just realized the
problem comes from the path task at the project scope level. This task would
lock up the files.
<path id="java.bin">
<fileset dir="${dev.dir.dist}">
<include name="**/*.jar" />
</fileset>
</path>

Subject: Re: About deleting jar files - i think it is a clear BUG
A possible solution could be to check if any of the files to be deleted are
in the classpath ( guess there is some API to poll the VM about that) once
we know they are in, we specifically tell the VM to remove them from the cp.
