[kepler-dev] Very strange issue with Kepler-1.0/Kepler-2.0 compatibility across actors

[Sean Riddle]

Well, I can see compiling it with 1.0 and then using the resulting
class file in 2.0 might be problematic. Is there a reason you're not
compiling this with 2.0? I tried it out under 2.0 (the development
branch, so it was compiled under 2.0 as well) and it worked.

(Forgot to cc kepler-dev at first)
