The number of patches that can accumulate in an update release Project's 
development forest prior to a release can be seen as a function of both 
time and the bar necessary to meet in order to enter the forest.

For most of its development time, that bar for issues entering jdk7u-dev 
was at effectively at P5 or higher, while the bar for this Project is 
effectively at P1. So while the timing hasn't changed between 7u and 9u, 
the bar necessary to pass to enter the forest has.

They can do so using the process outlined at

Indeed, every CPU release has been and will be developed in the same 
way. The scenery and actors may change, thanks to the Vulnerabilty 
Group, but the happy end won't. ;)

That's not correct. The OpenJDK 9.0.4 release was tested by developers 
at Oracle. Judging by http://db.openjdk.java.net/people it seems that 
Oracle employees represent at least a small part of the overall OpenJDK 
Community. ;)

Push requests can be tracked here: 

When they get approved, they appear here:

When they get pushed, they appear here:
http://hg.openjdk.java.net/jdk-updates and also at

For example, Martin's recent push is listed at

It is much easier to search JBS than mailing lists.

For example, https://bugs.openjdk.java.net/browse/JDK-8194739 is 
Severin's push approval for Zero fixes - it contains a justification, a 
link to the review thread (on the wrong mailing list, though: posts to 
jdk9-dev are unlikely to be seen by reviewers once the release reaches 
GA), and a 9-critical-approval label.
