[ros-users] rosjava and message constants

[Lorenz Mösenlechner]

Hi,

you are right. This has been a bug in the message generator. It has
sort of been fixed in release 0.1.2 so that it at least compiles. But
double quotes were still not added when being specified in the message
file. I fixed that in master now and it will be in 0.1.3

Thanks,
Lorenz
