Subject: year-end status of JSR 292 code pipeline

Enclosed it a summary of where we are.  (CC-ing mlvm-dev.)

Thank you, Christian, for pushing a mountain of code up the review trail.

I have spent the last four weeks earnestly using the JSR 292 APIs (draft though they are), and removing performance bottlenecks from a test application (Rhino, in fact).  The JVM-related results are in the four reviews I just sent out, which are bug numbers 6912062 through 6912065.

The fact that these bug numbers are consecutive suggests to me that I'm the only one in the whole company filing bugs, and therefore that it is quitting time...  We'll pick up the review and engineering activities in January!

Merry Christmas, and every other good seasonal wish,

-- John
