[JSR308] JDK 7 Milestone 4 is released, with support for type annotations

[Michael Ernst]

The JDK 7 Milestone 4 builds are now available for download.
It includes support for JSR 308: Annotations on Java types.
More details about JDK 7 M4 is available in Mark Reinhold's blog post:

Of course, you can always get the JSR 308 compiler directly from
  http://groups.csail.mit.edu/pag/jsr308/
That version gets bug fixes and new features faster, and it has a few
features that will not appear in the official JDK 7 version, such as
support for annotations in comments.
