> For larger feature sets like for the ServiceMix Full distro, the number of file handles
accumulated can exceed the OS defaults on some systems. The culprit seems to be that for every
bundle a Maven ArtifactResolver is used to download that bundle and the file used during that
process is not reclaimed until the goal finishes executing. I see the following in ServiceMix:
