update plexus-utils to avoid leaking processes in
CommandLineUtils.getSystemEnvars()
------------------------------------------------------------------------------------
Key: MNG-4219
URL: http://jira.codehaus.org/browse/MNG-4219
Project: Maven 2
Issue Type: Bug
Components: Performance
Affects Versions: 2.2.0
Reporter: John Casey
Not long ago, it was discovered that CommandLineUtils leaks processes in come
circumstances (in older versions of plexus-utils) because it fails to read
stderr. Later versions of plexus-utils (1.5.11 and above) have fixed this
problem.
Interestingly, Hudson has had a persistent problem with leaking processes on
the Windows slave VM out on https://grid.sonatype.org/ci/ - I'm pretty sure
this will help alleviate those issues. We should move up to the latest version
of plexus-utils to take advantage of this bugfix.
