[JSR308] Release 0.8.8 of JSR 308 specification, javac, Checker Framework, and checkers

[Mahmood Ali]

We have released version 0.8.8 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 many improvements that reduce false positives:  
support for Collection.toArray(), support for custom nullness  
assertions, and improved flow.  This release also includes bug fixes  
for the compiler classfile output.

The changlogs of the specification and the implementations appear below.

Please note that last release wasn't pushed properly to the website,  
but now we've ensured the correctness of the release process. The  
changelog of the previous release is also attached below.
