>             Project: Maven 2
>          Issue Type: Bug
>          Components: Plugins and Lifecycle
>    Affects Versions: 2.0.6
>            Reporter: Brian Fox
>            Assignee: Jason van Zyl
>             Fix For: 2.1.x
> It happens when processing resources, mostly for war projects although I'm not 100% positive
it's only wars. We see one of these warnings apparently for every file processed because sometimes
there are just a few and sometimes there are 1000s correlating to the number of files in the
project. So far it only happens on dual-core machines although not every time. It smells of
a multithreading issue.
> This issue has already been fixed in PLX-287. This MNG issue is to try and get that fix
into 2.0.x
