Diver is a dynamic analysis tool for Java that integrates scalable sequence diagram views with an interactive trace-focused UI in Eclipse. It provides sophisticated debugging support for understanding and exploring features of interest. Through a series of plugins for Eclipse, Diver allows you to: - easily record and capture traces of your running program; - interactively visualize, filter and share sequence diagrams of the captured traces; - selectively focus core Eclipse views on the traced code; and -seamlessly navigate between sequence diagrams and the trace-focused source code views.
