I'm looking for a way to output into file all methods, that are calling all methods in a specified class. I see that I could use ASM for this, but I cannot figure it out.

Example: class A has methods aA, bA, cA. class B calls methods aB -> aA, bB -> bA, cB -> cA.

I want to output "aB -> aA, bB -> bA, cB -> cA" into file.

My main goal is to trace all these calls from ExceptionFactory to service layer, and then output which service methods can throw specific exceptions.

The most suitable way for me would be, that it would run as a test, the file would be created during test phase.

EDIT: I actually don't know what class B is, I need to find out which class/classes calls class A.
