Very interesting initiative from Modelio : a new website, http://opensource-uml.org/, showcasing UML models derived from popular Java libraries and projects. So far they have the models for Ant, Jenkins, Junit and SWT but the list should be extended in the near future.
Obviously, this is something that can be done with other tools (like our own MoDisco tool) but I really like the idea of creating a site specifically for this as a way to promote modeling among Java developers (which is easier in a reverse engineering scenario than in a code-generation one).
FNR Pearl Chair. Head of the Software Engineering RDI Unit at LIST. Affiliate Professor at University of Luxembourg. More about me.
And it’s pretty cool that everybody can contribute a diagram of his or her favourite Java library.
