Merge ~vpa1977/ubuntu/+source/ca-certificates-java:dpkg-trigger into ubuntu/+source/ca-certificates-java:ubuntu/devel

[Vladimir Petko]

NOTE: Please do not merge this until all OpenJDK package updates are performed. This package breaks existing OpenJDK packages.

This change depends on openjdk-jre-headless triggering certificate updates in the postinst script. Prerequisite updates:
 - openjdk-8 [1] (merged)
 - openjdk-lts [2] (merged)
 - openjdk-17 [3] (merged)
 - openjdk-18 [4] (merged)
 - openjdk-19 [5] (merged)
 - openjdk-20 [6] (merged)
 - openjdk-21 [7] (merged)
Summary of changes:

  * Resolve circular JRE dependency (LP: #2003750, LP: #1999103, LP: #2004061)
    - debian/ca-certificates-java.postinst: remove setup_path, remove
      update_cacerts from "configure" stage.
    - debian/ca-certificates-java.postinst: do "fresh" update if cacerts file is not found. Certificates are refreshed only in response to the trigger activated by OpenJDK packages.
    - debian/ca-certificates-java.postinst: fix cacert enumeration command for Java 8.
    - debian/control: remove JRE dependency.
    - debian/control: add Breaks condition.
    - debian/tests: add smoke tests.
    - debian/ca-certificates-java.triggers: remove file trigger /usr/jvm.

> This package breaks existing OpenJDK packages.

Well currently debian/control lists the Breaks but they are commented out! Provided we actually land the Breaks: correctly, we don't have to wait for all openjdk updates before landing this (though it will make each of those JREs uninstallable in -proposed and break builds of anything build-depending on them, so we should make sure *default*-jre is sorted before landing this.)

I will wait for the ppa to finish building OpenJDK 18 and will uncomment the Breaks section.
We will have to land all the JDKs first so that they could build themselves from unbroken build.

Uncommented Breaks, uploaded new version of openjdk-19. Once it builds I will update autopkgtest results.

closing the version number gaps in the Breaks: is the last thing to change before sponsoring.

 Description: Common CA certificates (JKS keystore)
  This package uses the hooks of the ca-certificates package to update the
  cacerts JKS keystore used for many java runtimes.
