jexec is legacy, should probably be removed [1].

It's good that the issue has been tracked down but I'm curious why it 
was initially intermittent. I would have expected it to fail every time. 
Also just to say that jlink goes out of its way to ensure that 
jspawnhelper has execute permission so I assume the issue is something 
copying a run-time image and not preserving permissions?
