[kepler-dev] Kepler build problem: Bad Version number

[Matt Jones]

Hi Christopher,

Did Chad's recent checkin removing the Java 1.6 class help with your build?

I also haven't seen the NMI build logs coming through.  Chad or David,
could one of you look into why we aren't seeing NMI builds?  Thanks,

Matt
