"From my short experience with Enterprise Java years ago, such deep callstacks are usually symptomatic of code that does far more indirection than actual work --- hundreds of tiny methods that have maybe a statement or two and then call another one. "

This isn't just a Java thing. I've seen plenty of TDD code written with other languages where there is basically the same thing (so the code can be "testable"), but also with heaps of redundant tests that just add dependencies and maintenance overhead without providing much value.
