> When a maven plugin tries to load a resource(file) from a plugin dependency defined in a project pom file and the path to that resource begins with 'slash' / then the resource is not found. The code uses the Plexus ResourceManagers
> Example code that works in 2.2.1 and earlier and fails in Maven 3.0-alpha-5. If resource is in root of jar and configFile begins with forward slash then we get ResourceNotFoundException.
