I wonder if the core technical issue is this: Debian stretch currently
packages OpenJDK 8 8u212-b01, when it should be packaging 8u212-b03 or
8u212-b04 (which one isn't clear, the release announcement
<https://mail.openjdk.java.net/pipermail/jdk8u-dev/2019-April/009115.html>
was for 8u212-b03, not for 8u212-b04 or 8u212-ga).

My understanding is that 8u212-b01 is a version identifier created by
the jdk8u project, and based on a quick check, it matches what Debian
identifies as its upstream sources (except for some stripping of system
library components). But it's not the most current release.

It's one of the challenges, the rest of the world doesn't necessarily know about the new `-ga` tag that we use to designate releases, so we need to go and help them.

Let's be clear about what the new (as in "additional") -ga tag is, in order

to avoid the misunderstanding (that you can see in other threads) that

somehow OpenJDK has just now started declaring releases:

The notion of a "-ga" tag was added recently as a convenience mechanism

to help people "identify snapshots of GA releases in Mercurial history without

having to know the build number of the GA release".

(see

https://mail.openjdk.java.net/pipermail/jdk8u-dev/2018-October/007940.html

for initial discussion).

To quote from there:

"For example, to obtain JDK 10.0.2 GA sources today, one issues the

`hg update -r jdk-10.0.2+13` command. With the proposed

enhancement, `hg update -r jdk-10.0.2-ga` could have been used."

[GA and other] Releases

existed long before this tag was added, and every [GA and other] Release

has a known tag number.

The "-ga" tag is a welcome addition, and makes it much easier (fewer steps)

to find the sources for a release, as well as programmatically watch

for ones to appear.

I've also replied separately to this thread (with a meeting request) but cut out the OpenJDK mailing lists as it's really the Debian distro list that we should be discussing this on.
If folks feel otherwise, let me know and I'll CC these lists back in.

Cheers,
Martijn
