I have done this for C code. I will sometimes print off sections of a call tree and make notes on it to keep track of what I have found about what updates what as I work backwards from the point of failure.

I have also used the 'call hierarchy' and 'find usages' features in IntelliJ to help me navigate around Java code.

I appreciate your point that more dynamic and feature-rich languages are much more difficult (if not impossible) to analyze statically.
