Comment 26 for bug 1723198

[JUSTIFICATION ZESTY] (Part 2)
----------------------
Release upgrade using "ca-certificates-java" package currently found in -updates and upgraded to zesty-proposed during the release upgrade.

The upgrade went well installing "ca-certificates-java" version "20161107ubuntu1" which now depend on openjdk-8 instead of -7-, fixing the trigger failure.

[Xenial]

ii ca-certificates-java 20160321 <== Currently in xenial-updates
ii openjdk-9-jre-headless:amd64 9~b114-0ubuntu1

(Note: This "ca-certificates-java" package version installs openjdk-9 part of 'universe' (as mentionned in [Regression potential] section) as oppose to its successor that will install openjdk-8 part of 'main'. This is not considered a blocker after a conversation with slangasek (SRU verification team).

[Zesty]

ii ca-certificates-java 20161107ubuntu1 <== Currently in zesty-proposed
ii openjdk-9-jre-headless:amd64 9~b161-1

To summarize the possible scenarios:

* If Xenial users has "ca-certificates-java" package lower than "20160321ubuntu1" installed, they will have openjdk-9- and it will follow during the release upgrade to Zesty.
* If Xenial users installs "ca-certificates-java" for the first time with version "20160321ubuntu1", they will have openjdk-8- and it will follow during the release upgrade to Zesty.
* If Xenial users already have "ca-certificates-java" intalled and upgrade to version "20160321ubuntu1", they will keep openjdk-9- and it will follow during the release upgrade to Zesty.
