10.9 update

[Rick Hillegas]

I have created a 10.9 branch and built a release candidate. However, I 
do not expect to publish this candidate. Some late-breaking performance 
measurements show a large, unexpected throughput drop for concurrent 
users of identity columns. See DERBY-5471 and DERBY-5780. It is likely 
that we will want to address this regression before producing a new 
release. The fix, of course, will have to be ported to 10.9 now that the 
branch has been created.

Please stand by...
Thanks,
-Rick
