Description

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.
