Scalameter for java code

Please note that I've worked on version forked from http://axel22.github.com/scalameter/.
Also, I have a NullPointerException at the end of regression tests, even with scala code coming from HTMLReporter.scala at line 167. I have not been able to determine if it comes from my code, or my computer...
Are you sure this works correctly? The ordinary `DSL` trait in `dsl.scala`, does not descend in `context`.
A sequence of tests like this:

    class G extends Group {
      class CurveA extends Using<Object, Object> {
      }
      class CurveB extends Using<Object, Object> {
      }
    }

should produce a tree like this:
    
    G
    |-CurveA, CurveB

and not:

    G
    |-CurveA
    |    |-...
    |-CurveB
         |-...
