JENKINS-12735 enabled (down/)upstream builds to work with version ranged dependencies but I noticed that starting from revision 1.480 I noticed that some of our builds were stuck in the queue forever.

JENKINS-15367 is fixed the upstream builds so that I have isolated the problem to be caused by cyclic dependencies which of course should be fixed. This is way better that having the system repeatedly be building these projects but it is a bit unclear what the problem is when the build is said to only be depending on itself.

The job will build fine when job causing the cycle is disabled. I don't have an exact opinion how this behavior should be altered but currently I have to be purging the queue manually util the cycle is dismantled and surely this isn't build automation at it's best.
