Public bug reported:
1. Steps to reproduce:
Depending on which packages you select for installation, it is possible the
postinstall and trigger for ca-certificates-java run before Java has been
installed. This may be possible to trigger with more combinations, but I've
found
$ sudo apt install maven openjdk-8-jdk
where the issue is reproducible. Running this on an out-of-the-box system, for
instance a VM will trigger the issue.
See installation.txt for the full output of running this command, but the
important section is this one:

/var/lib/dpkg/info/ca-certificates-java.postinst: line 53: java: command not
found
/var/lib/dpkg/info/ca-certificates-java.postinst: line 66: java: command not
found
done.
(...)

E: /etc/ca-certificates/update.d/jks-keystore exited with code 1.
done.
Setting up openjdk-8-jre-headless:amd64 (8u40~b09-1) ...

provide /usr/bin/rmid (rmid) in auto mode
update-alternatives: using /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java to
provide /usr/bin/java (java) in auto mode
2. Expected behaviour:
Packages are installed in the correct order so that they can assume their
dependencies are present when for instance attempting to run postinstall. (So I
don't really know whether this issue is truly caused by ca-certificates-java or
by the priority/order of packages assigned by apt or something else.)
3. Actual behaviour:
As we see both the postinstall and trigger is attempted run before java has
been installed, which results in /etc/ssl/certs/java being an empty directory.
Effectively this means Java doesn't know any certificates so for instance
creating a connection to an HTTPS-url will fail.
4. Attempted workaround:
As a workaround, I figured I could reinstall ca-certificates-java and maybe
that would work.
$ sudo apt install ca-certificates --reinstall
(...)
Processing triggers for ca-certificates (20141019) ...
Updating certificates in /etc/ssl/certs... 0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d....
done.
While this gives me the cacerts file at /etc/ssl/certs/java/cacerts we can see
that it contains no certificates:
$ keytool -list -keystore /etc/ssl/certs/java/cacerts
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 0 entries
(The default keystore password is of course "changeit")
