This is a follow up of https://www.eclipse.org/forums/index.php/t/1091909/

the approach described there but it has a downside:
adaptables

AnnotationModel does 

 private ISourceNode findSourceCoverageForEditor() {
    if (editor.isDirty()) {
      return null;
    }
    final IEditorInput input = editor.getEditorInput();
    if (input == null) {
      return null;
    }
    final Object element = input.getAdapter(IJavaElement.class);
    if (!hasSource((IJavaElement) element)) {
      return null;
    }
    return findSourceCoverageForElement(element);
  }

so the problem is that you can have only one adapter factory from 
FileEditorInput to IJavaElement

maybe it would be easier to customize with

editor.getAdapter(IJavaElement.class);
before asking for editor.getEditorInput();

i also wonder if there could be a more general solution to get custom languages into emma so that they also show up in the coverage view

do you have any hints where to start looking

thanks
