JDK 7 build 27 is available at the openjdk.java.net website

[Rob Ross]

Sorry to ask again, but I'm trying to learn how this works :)

I had read through the archives regarding the repository process  
flow, and know there are several levels with gatekeeper repositories  
before the "master" repository, which I thought was at jdk7/jdk. I  
also thought that code does not get checked into this repository  
until it's gone through several gatekeeper repositories and been  
tested, reviewed, etc. So things would only get checked into master  
in well defined circumstances.

If my understanding of the above is not correct than what follows is  
also not correct. I understand about creating a changeset tag to be  
able to recreate that code in that moment in time, but I didn't  
understand where Xiomara said

"There is no difference in the code at this point.  Once integrations  
start to flow into the master repositories then the two below will  
defer, hence the reason to include the change set rev for this  
particular build number."

Wouldn't any changes that flow into the master repositories be based  
on code originally part of this tag, that had been tested, modified  
if necessary, and eventually approved? So any such changes in the  
master would be (excluding regressions) a positive development?

This is the opposite of how other SCM systems work, where the head/ 
top is usually in an unstable state due to active checkins, and you  
want to pull a stable release tag that has been created to mark a  
milestone during development - is this correct?
