What the heck "runtime.start() should not throw anything other than AdminException!" ?

Hi guys

Like you , I don't like too have errors preweekend, but this one is totally unknown to me. It became visible after a commit with domain model and mf changes....and I didnt do anything extraordinary...so totally wondering where this came from.

A clean deployment did not help, earlier this weeks I did overwrite the jar files...but that went okay And now (several commits later) I get this one...Any preweekend hero's?
