Question

Is there an IDE/Tool/script/something that can show call hierarchy and/or data flow in Scala+Java programs (preferably from source code).
Or (as a backup plan) is there a tool that can show it using Java bytecode? (And preferably give the option to go to source code, if provided by user).
All that, preferably integrated into an IDE and/or Maven 🙂
The requirement to support Scala is crucial in this question. I Already know of and use such tools for Java, in 3 IDEs. They do not work very well (actually: at all) when Scala is involved.
TIA

Poor man’s call hierarchy: Comment the method out and see where your red squigglies show up. [/me ducks]
