I was thinking just do it for 7, and not bother with 6:

1. OpenJDK 6 does not seem to be perfectly synchronized with Oracle JDK 6 in my experience (maybe this has changed recently), so its versions of javac might be missing 
recent bug fixes.

2. Even if you want to build for JDK 6, you can use javac from OpenJDK 7 safely; just specify -source 6 -target 6 (which you should do anyway).

Agreed - these might implement APIs which are not yet standardized. I was bringing up the suggestion of publishing langtools now because JDK 7 is officially published, so 
there is no risk of advertising a version of javac which implements an ultimately rejected aspect of Project Coin or something like that.

Anyway when JDK 8 is released, the components of langtools would be available as modules (currently named jdk.compiler, jdk.javac, etc.) and the manner of publishing 
would need to be revisited.

Well, they are if you add the langtools JARs to your classpath, assuming it continues to be compiled with -target 5 and avoid JDK 6+ APIs.
