> When I started to look into finding common code between ant, plexus, m2 and
> cruisecontrol, I found a couple of differences that I think need to be merged
> back into commons-exec.
> In particular it seems like this plexus-util change [1] contains a threading fix
> which should also be backported to commons-exec. I think we are hitting it now
> in CruiseControl in some rare cases: executed process is ant which forks and
> spawns a separate process. This makes getInputStream().close() hang, and I think
> your change would fix it.
> I haven't yet worked on it, nor wrote a test case. Would appreciate input from
> trygvis as he's the one who made the fix for plexus.
