screenshots and testcase to reproduce issue

Description of problem:
java-latest-openjdk-headless RPM packagedoes not require fontconfig, however certain java programs will not work unless it is installed.

I suggest fontconfig be added as a dependency to java-latest-openjdk-headless

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Run attached test program without fontconfig installed.
2. Run attached test program with fontconfig installed.

Actual results:
It crashes without fontconfig

Expected results:
RPM should require fontconfig if it is required to run java programs.

Additional info:

Comment 1 Petra Alice Mikova 2019-05-20 11:07:25 UTC

the headless package does not require fontconfig intentionally, because the fontconfig and its dependencies pull in a lot of X packages, that makes the installation 'not so much headless' anymore.

repoquery --requires --recursive --resolve fontconfig | grep X

However, the fontconfig is a dependence of java-latest-openjdk base package, so installing java-latest-openjdk should be the correct solution for your problem.

Comment 2 Steffen Mikkelsen 2019-05-20 11:13:14 UTC
I have tested on a minimal install on Fedora 30 (x86_64) without X11 installed. I do not see any dependencies from fontcontig to any X11 libraries. 
You can also see the dependencies here: https://fedora.pkgs.org/30/fedora-x86_64/fontconfig-2.13.1-6.fc30.x86_64.rpm.html

Comment 3 Petra Alice Mikova 2019-05-20 12:24:27 UTC
Have you also checked the whole dependency tree of fontconfig dependencies? Fontconfig itself does not pull X11, but it's dependencies do, as far as I know. Maybe other people involved in OpenJDK packaging will have more information about this - Severin, Jiri, any thoughts?

Kind regards,

Comment 4 jiri vanek 2019-05-20 12:38:22 UTC
I'm also hesitating with adding the fontconfig to headless depndence:
 repoquery --requires --recursive --resolve  fontconfig | wc -l

 repoquery --requires --recursive --resolve  java-1.8.0-openjdk-headless | wc -l

That is big dependence chain overhead. Maybe jdk can throw better exception? Like "install font config" ?

Comment 5 Steffen Mikkelsen 2019-05-20 12:55:46 UTC
Using your repoquery command I also get a ton of dependencies for fontconfig. 

However when running "dnf install fontconfig" they are not required by dnf. And no the packages are not installed already. 

I have attached the list of installed packages (dnf list installed) on my system so you can see that fontconfig is installed without any X11 dependencies.
The dependencies that were installed:

Comment 7 Severin Gehwolf 2019-05-20 13:15:41 UTC
First things first:

$ rpm -q --requires java-latest-openjdk-headless | grep \.so
nss-softokn(x86-64) >= 3.43.0
$ rpm -q java-latest-openjdk-headless

This is wrong. It's bug 1702324. I'd fix that one for JDK 12 first and re-evaluate.

Comparing JDK 11 (which has this fixed) and JDK 12 I see these differences:

Installing package fontconfig, which drags in at least one font, fixes the issue on JDK 11.

It seems OK to add fontconfig package to the list of required packages for openjdk. Here is the list of additional packages being dragged in for non-headless java-11-openjdk (after fontconfig is already installed):

Comment 10 Ben Cotton 2020-04-30 21:58:03 UTC
This message is a reminder that Fedora 30 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '30'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 30 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
