Dear Arjan, well, I'm also creating the function set and type set out of a couple of Java classes in order to let ECJ generate feasible method call sequences. The point is that not each Java class possesses a (parameter-less) default constructor -- consequently, no terminal will exist in the terminal set for thes classes. Would be nice to see a configuration or specialized tree building algorithm for this issue.

Java has a terminal node for every node, but I still had to do some funcky stuff of course. I know how to write your own, so if you need some tips for that I can show my version. Otherwise someone else can help you.

Or are there alternative tree builders known/available that would do this job? (Of course, it is possible to build trees using the function set and type set that doesn't contain terminals for all types. But actually, I'm not able to get ECJ do this.)
