Yeah I missed that check too. I'm very much in favor of being able to
use an older (or newer) JVM in the JDK7 image. Triage is one
important reason but another is the non-synchronous putback schedules
of the jdk and hotspot workspaces. There will be a period of QA time
when the JDK uses an older VM (or vice-versa) just because of the way
our process works.
I think the jdk code should probe the JVMTI version and use whatever
is available. I'm in favor of modifying the code in debugInit.c to
verify only 1.1 and then dynamically probe before using any 1.2
features (and so on in the future).
In the past I don't think we've done this. Instead we've usually just
kept back the jdk changes until the hotspot changes made it into a
promoted build.
One other thing is the regression test. The debugger tests are in
jdk/test/com/sun/jdi and it is important to add a new test, or add to an
existing test. If you are pushing the jdk changes before the VM changes
have made it into a promoted build then I guess you'll need to hold off
pushing the test (or add it with the @ignore tag, removing it later via
a different bugID).
