I haven't found any more simple way to traverse the code according to the flow.
Only insignificantly small amount of Java methods require second or more passes to complete the flow graph.
Out-of-order construction of auxiliary graph and then traverse in the right order and transform each block is much more complex.
The API also does not allow to get information about existing block beeing built, so there is for example no way to get know that it is a try-start or try-end block.
