Review comment:
I had a conversation to discuss about the exception handling with Hunter. He
suggested keeping the code as is. This is why I did not change the current code
in getWorkflows().
If we would like to change that API, we could just do this getWorkflows()
calls getWorkflows(0L). timeout = 0L means wait with no timeout. What do you
think?
