I am pleased to announce that binary builds of the JSR 308 Reference
Implementation are available at http://jdk8.java.net/type-annotations/.

Please see the Type Annotations project page for a link to the JSR 308
Specification. There is also a changelog, which is important to review
as there have been significant spec changes in 2012.

The builds were generated from the type-annotations/type-annotations
forest on 9/9. This forest is regularly updated from jdk8/jdk8 and
jdk8/tl.

If you want to play with repeating annotations, check out http://jdk8.java.net/type-annotations/ ... thanks to superior code wrangling by Joel Franck (repeating annotations) and Werner Dietl (type
annotations), support for repeating annotations on declarations is included in the build.
