>
> The submission of the streaming job is not thread safe. 
> That is because the class StreamJob is using the OptionBuilder which is itself not thread safe. 
> This can cause super tricky bugs. 
> An easy fix would be to simply create instances of Option through the normal constructor and decorate the object if necessary. 
> This fix should be applied on the functions createOption and createBoolOption.
