Optimizer patch reviews? (DERBY-781, DERBY-1357)

[Army]

I posted two patches for some optimizer changes a little over a week ago: one 
for DERBY-781 and one for DERBY-1357.

Has anyone had a chance to review either of them, or is anyone planning to?  I'm 
hoping to have these reviewed and committed sometime in the next few days so 
that I'm not forced to try to address issues at the last minute for the first 
10.2 release candidate.

Optimizer changes can sometimes be rather tricky, so the sooner the review--and 
the more eyes on the code--the better.

The DERBY-1357 changes are quite small and are very easily reviewable, while the 
DERBY-781 changes are more involved.  Anyone have some time to review either of 
these patches?

Many thanks,
Army
