File Parameter Evaluation

I am developping a plugin have as configuration a File.

In the Test phasis, I encounter some trouble with File Resolution.
My dependency are :

• org.apache.maven.shared:maven-plugin-testing-harness:1.1

In the org.codehaus.plexus.component.configurator.converters.basic.FileConverter provided by Plexus-container-default-1.0-alpha-9-stable-1.jar,
The method fromConfiguration() calls expressionEvaluator.alignToBaseDirectory( f );
In case of Test , the expressionEvaluator is org.apache.maven.plugin.testing.ResolverExpressionEvaluatorStub.
The code is as follow :
public File alignToBaseDirectory( File file )
{
if ( file.getAbsolutePath().startsWith( PlexusTestCase.getBasedir() ) )

{ return file; }

else

{ return new File( PlexusTestCase.getBasedir() + File.pathSeparator + file.getPath() ); }

}

Two Bugs :

• All path which do not start with TestCase Basedir are assumed as relative path based on basedir. Why not, but it not allow to test Absolute path.
• The concatenation with the Basedir is done with File.pathSeparator ( : under UNIX and ; under Windows) instead of File.separator ( / under Unix and \ under Windows ).
