[JSR308] Release 0.8.9 of javac, Checker Framework, and checkers

[Mahmood Ali]

We have released version 0.8.9 of the JSR 308 specification and
implementation and of the Checker Framework.  You can always review
the latest version of the specification at: http://groups.csail.mit.edu/pag/jsr308/specification/java-annotation-design.html
; and download the latest version of these tools at:http://groups.csail.mit.edu/pag/jsr308/
.

The JSR 308 implementation is a backward-compatible extension to
javac. The Checker Framework makes it easy to write a tool that finds
or prevents errors; the tool is expressed as a type-checker for a
pluggable type system.  The Checker Framework distribution includes
sample checkers.

This release includes some space optimizations and many bug fixes  
related to conformance of classfile to specification and correctness  
of the flow sensitivity analysis.

The changlogs of the specification and the implementations appear below.
