Bug 9169: jobcoordinator null safety

Eclipse's JDT compiler (javac alternative) can guarantee that there are
no more NullPointerException possible in the jobcoordinator code with
this.

However external code calling into this code (e.g. from genius and
netvirt) which has not yet been null safe enable can still cause
NullPointerException, so this cannot prevent e.g. Bug 9238, yet.
However it can prevent it in the future, once all is null safe!
