Maven Build Fails for CampBX

[timmolter]

It doesn't like the import com.sun.istack.internal.NotNull; in CampBX.java.

I think it has to do with Java 6 compiler level, which I think we want to keep.

I'll fix it. These are just marker annotations, to be read as documentation by users, not read by the code.

If this is a blocker, they may be safely removed immediately.

Done. I added JSR-305 (31 kB).

These annotations are currently not strictly necessary: they currently only serve as documentation (ie. they are meant for the human reader and are not read by Java reflection). But they might be read by reflection in the future.
