So many great comments here about UML tools. I also had the misfortune of using them. I agree that details of classes internals was rather intrusive info to digram out. And instead of helping it actively harmed system understanding.
Lately I have been able to generate diagrams after the fact for my Java projects. Jdeps provided dependency graph for whole project at package or class level in dot file format and then graph can be reduced and plotted by graphviz tools. Not as rigorous as UML or visio but still pretty good for logical understanding or finding cyclic dependencies in code.
