I get this when compiling my project using Eclipse 3.6 only (not 3.5) in the sdf2imp.eclipse task.

Strange problem. Is there anything in the error log like “Unable to initialize dynamic builder” ? [edit]Actually, “Unable to initialize builder” shouldn’t be the problem here. But maybe there’s something else?[/edit]
