I posted a heads-up to the maintainers about this and so far had one 
reply suggesting that backporting tojdk25u should not be problematic.

So, Mat, if you can go ahead and prepare the two backport PRs I'll 
review them (if a review is needed -- i.e. only if they don't apply 
cleanly) and we can then add a jdk25u backport request label to them and 
pursue the normal backport approval process.

Ioi, one question: was there a reason to set the backport JIRA target to 
25-pool rather than 25u? No implication that this is wrong -- I just 
don't really know what that target means.
