Move CTF compilation away from ANT compiler task to another, perhaps JCI

There is a desire to move away from the test framework's use of the ANT JavaCC compiler task for compiling the output of the source generation. JCI is one alternative. To use JCI, we'd need to use one of the implemented compilers, groovy, janino, or eclipse. Is the Eclipse compiler the one that would be preferred? (Interestingly, I don't obviously see a way with JCI to use the Sun Java javac compiler, but I've only looked at it for a couple minutes so far.

There are no public releases of JCI yet.

I haven't marked a "fix version" for this issue as I'm not sure when this work can successfully be targeted. But by creating an issue at least there's an area to track investigations, disucssion, and resolution.
