Java type annotations: early draft review
The type annotations specification ("JSR 308") is in Early Draft Review. This is an opportunity for the public to comment on the proposed specification, so that it can be improved before being incorporated in the Java language.
Oracle has announced that they intend to include, in JDK 8, support for type annotations. Currently, Java only permits annotations, such as @Deprecated or @Override, to be written on declarations. The ability to write annotations on type uses enables improved documentation and bug detection. One example use is the Checker Framework for pluggable typechecking. Note that the Checker Framework is a third-party tool and not part of the Java language proper.
