> But the build completed with no errors. The build that thrown the exception 
> happened afterwards, and in this particular case, all entries where already 
> in the cache, loaded from the build from a previous project - there were no 
> download messages. I wonder if the loop checks are being done in the first 
> scenario (as dependencies are being downloaded) but not in the second (when 
> they are read from the cache) ?
> I don't have a unit test case ready, as this is part of a really large build. 
> I will post one if I can isolate the problem.
> Here is the code causing the recursion:
> 133:   private void addToSortList(List sortedList) {
> 134:        for (Iterator it = loopElements.iterator(); it.hasNext();) {
> 135:            ModuleInSort moduleInLoop = (ModuleInSort) it.next();
> 136:            moduleInLoop.addToSortList(sortedList);
> 137:        }
> 138:        if (!this.isSorted()) {
> 139:            sortedList.add(module);
> 140:            this.isSorted = true;
> 141:        }
> 142:    }
> There is no check inlines 134-136 to make sure it is safe to keep the 
> recursion. According to Xavier:
>   "I think an infinite recursion will occur "only" if a ModuleInSort can be 
> found among the loopElements of any of the ModuleInSort of its loopElements, 
> recursively. Having a junit test case to reproduce the problem may not be 
> easy, but we can add a guard against this infinite recursion."
