I just wanted to bring this discussion up before this code went too far 
as to whether it makes sense to add a separate generator to the MAVLink 
project that's written in Java. That means there will be two separate 
generators for MAVLink. Any changes to the protocol then need to be done 
twice. Also the Java implementation isn't finished. It seems like since 
most of MAVLink generation is merely text copying, it should be fairly 
easy to move your work into pymavgen instead of leaving it separately. 
Of course, since you don't know Python, that will make things more 
difficult as someone else will need to step up to the plate. I'm of the 
opinion, given the number of developers for MAVLink, that adding a Java 
port will be unmaintainable in the medium- to long-term.
