stephen mallette updated TINKERPOP-1106:
----------------------------------------
Description:
Because the last message in a result is sent before commit as the terminating
message, a failure on {{commit()}} will send another message, but the driver
won't be looking for it and it will not register as an exception on that
request.
Seems like the solution would be to save the last message until after commit,
and if the commit fails, you would send the error back otherwise send the last
message. In this way the protocol doesn't have to change.
Also need to determine if exceptions prevent additional iteration of results
back to the client as discussed here:
