When multiple jobs have a common descendant, the 'next build number' for the descendant job is shown wrong in the console output of the parents.
eg., if j1, j2 and j3 has c1 as descendant.
c1 has got 100 successful builds.
j1, j2, j3 shows 101 as the next build number for c1. it ideally should be unique for all the parent builds.
