>
> The class org.apache.maven.plugin.surefire.report.TestSetRunListener has a 
> lot of checks like this:
> {code:java}
> if( field != null )
> {
>     // do something with field
> }
> {code}
> This can be simplified by providing fallback implementations for the fields 
> being used by TestSetRunListener.
