package ca-certificates-java 20190909 failed to install/upgrade: installed ca-certificates-java package post-installation script subprocess returned error exit status 127

[Alexey Morozov]

The bug appeared during the *clean* installation of openjdk-18-jdk. The package was installed using `apt install openjdk-18-jdk --no-install-recommends`. It's important to mention that no previous java has been installed, so no `java` executable existed on post-install.

The cause of the problem is:

Processing triggers of ca-certificates (20210119ubuntu1) …
Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...

/etc/ca-certificates/update.d/jks-keystore: 82: java: not found

done.

I have filed https://bugs.launchpad.net/ubuntu/+source/openjdk-18/+bug/1965987
under Openjdk-18 for Jammy but it's probably the same bug.
Imo the ca-certificates-java is not 'bugged', it's not adapted to Java 18. If Ubuntu wants to distribute Java 18 before Debian is ready to do so, it should maintain the ca-certificates-java package.

Status changed to 'Confirmed' because the bug affects multiple users.
