Ken Hu commented on TINKERPOP-3040:
-----------------------------------
It's been a while since I've taken a look at this part of the code myself so I
can't quite remember the details.
We depend on the local evaluation to tell us if the multiline script is
fully-formed and complete so that it is ready to be sent to server. The way the
parser is setup now in Groovy 4 may require that evaluation to happen twice per
line. In the past, there were alternative parsers for Groovy but I didn't look
to see if alternatives were available in Groovy 4. That is possibly one thing
to check on.
If you are looking for a way forward for this issue, the easiest thing to try
would be to add a "catch(RuntimeException)". Of course, this wouldn't always
work since it might actually be a real error. But, it might be enough to
satisfy your use case.

> It appears that if an exception occurs when the remote console is executing a
> command locally then it won't send that query to the server.
