That is actually about half of what jdk7 or icedtea (disregarding
openjdk import changes) have been seeing. So I do think it is a
significant amount of changes. It would certain help with getting a
better view of how changes relate to each other.

Ah, that is a bummer. I had assumed that the teamware history only
included stuff starting with the public release of openjdk7. Isn't there
any way to "replay" the patches starting at that point and post those?
rcs and cvs also maintain history on a per-file basis, but with some
scripting tricks it is still possible to reconstruct cross-file
changesets from them mostly. If that is impossible, could you start
posting patches to the jdk6-dev when you apply them to your repository?
So the chunks are smaller and can be commented on more timely than when
you do full bxx code drops?

Thanks,
