Current line / Java Class is not shown as a compilation unit

I have a pretty big ejb application comprising of more than 20 modules. I recorded the application for use cases and am playing back in chronon debugger on eclipse. I went to the concerned method and clicked on "run to method". Chronon opened one more editor view for the same class but as a non-compilable unit. So, I am able to view the chronon recorded information but not able to navigate methods, etc., Why is this happening?

PS:- My entire project is build using Maven.
