Christopher Smith commented on TINKERPOP-3238:
----------------------------------------------

I think I'm the one behind the ticket here, and I would clarify the request to 
at a minimum implement {{Failure}}, which is explicitly guaranteed by the API. 
Use of {{FailException}} itself would be a substantial improvement on that, 
because some functional/reactive pipeline DSLs don't provide a mechanism for 
"handle failure of type {{X does-not-extend Exception}}".

> {{fail()}} step throws a {{FailException}} in embedded mode - it's documented 
> as such. For remote with websockets you get a 595 error code but a 
> {{FailException}} will not raise even for Java. For HTTP you get a regular 
> old 500 exception with an error message that says the fail triggered. Clarify 
> this situation in the documentation and consider an approach that can 
> actually raise a {{FailException}} in java for the 595.
