What do you mean by exceptional block graph? How can i imagine that?
After i have seend that i can not identify pure blocks in jimple i am
looking for alternatives.
Perhaps it will work if I transform my argument block in the frontend into

try { ....} catch (Throwable t) {throw t;}

I suppose that this block must have a representation in jimple.

My problem is that i am totally new to jimple and have some
difficulties to reconstruct the transformation from my JastAdd-AST to
