I think it would be nice if cTAKES aimed for zero warnings. Right now, I see 3388 warnings, though this number is probably different for you depending on your settings.
One step we could take in this direction is making sure that we all see the same warnings. For Eclipse, this would mean making sure that all cTAKES projects have exactly the same .settings/org.eclipse.jdt.core.prefs. For an example of one possible set of warnings we could choose, see ctakes-temporal/.settings/org.eclipse.jdt.core.prefs. I don't feel strongly about exactly which warnings are on or off, but I would love to see us be consistent across the different cTAKES projects. Steve P.S. On the Maven side, it looks like we're already using -Xlint with the maven-compiler-plugin, so that's good. But I suspect most people are like me and they won't fix a warning unless there's an annoying little yellow sign in Eclipse. ;-)
