After a Jenkins upgrade from 1.544 to 1.562 all multi-platform jobs started to abort themselves for no apparent reason.

We have jobs configured to build on three platforms, Win, Mac and Linux. As soon as one of the platforms are ready all the others aborts themselves. This is an extract of the behaviour from the log:
