http://openjdk.java.net/projects/jdk7u/groundrules.html Rule 3 Changes submitted for a JDK 7 Update forest MUST go through code review, and MUST be approved by the maintainer for that forest. The maintainer of a forest MAY delegate that authority, allowing for approvals to happen in a more finely granular fashion - per repository, for example. Rule 4 Maintainer approvals for public JDK 7 Update forests MUST take place on the jdk7u-...@openjdk.java.net mailing list. Code reviews SHOULD take place on that list - if they take place somewhere else, as part of the approval request a URL for the public code review MUST be provided. > > > Also, AFAICS, this only just went into 8-tl: > > http://hg.openjdk.java.net/jdk8/tl/jdk/rev/e7f813f2ea86 > > I think it should have some time to soak there before going into > > 7u. > > Again, why? These are build changes. They either work or they don't. And if they don't work, putting the same broken fix into multiple repositories creates more work in fixing it and breaks the build for more people. Also, just because something does build doesn't mean a change hasn't subtly changed something. We're already having issues with the original addition of this stripping, as GNU/Linux distros have their own methods of handling debuginfo and stripping so don't want this being done by the JDK build. Also, we've traditionally had a period of allowing changes to soak from when OpenJDK7->OpenJDK6 backports were done, and I think this was helpful. AFAICS, this change is not even completely in tl at the moment (just the jdk & root parts are). So I doubt it's had much testing. > > Dan > > > > > >>> > >>> On 3/16/12 1:58 PM, Daniel D.
