Re: JavaTranslator vs. GroovyTranslator and Gremlin bytecode compilation speeds.

[Vladyslav Kosulin <vk...@gmail.com>]

I love the idea, but here are my concerns:
How can difference in client and server JVM compiler versions affect 
bytecode evaluation by a server? What if client was compiled with newer 
compiler, and the server does not recognize the version of bytecode sent by 
the client? I would assume it will fail. And what will happen when 
serialVersionUID differs if client and server are on different versions of 
application (not the tinkerpop version)? There will be no problem with 
groovy string in either case, but the java bytecode evaluation may fail, 
right?

JVM versions won't matter. Gremlin bytecode is evaluated by Gremlin so, if
there were versioning issues they would be specific to TinkerPop
versioning. A client on TinkerPop 3.2.5 sending bytecode to TinkerPop 3.2.4
could potentially have a problem if the it used some new feature of 3.2.5
that wasn't available at the time of 3.2.4. As we look forward with
bytecode and serialization/protocol issues we will need to do more with our
versioning of it so that 3.2.5 could communicate without hassles to older
versions. This is a problem more generalized to remoting than just
something specific to bytecode.
