I have a 3rd party app that use a Java GUI, so it won't run on a headless JVM. I had
it working until I installed a different app using dnf. It overwrote my JVM with a
headless one and now the Java GUI app is broken. Is there a way to install/register a
non-headless JVM with Fedora so it won't keep installing the headless JVM?
Thanks

Uhm, I think you'd need to simply exclude the JVM stuff from dnf by
either using an "exclude=" clause in your /etc/dnf/dnf.conf or adding a
.conf file in /etc/dnf/protected.d, e.g.
# cat /etc/dnf/protected.d/java.conf
java
(assuming you have the dnf "protected_packages" plugin installed).

Sounds like you are running into the problem described here:
https://bugzilla.redhat.com/show_bug.cgi?id=1302448
You should be able to use the `alternatives` command to switch
/usr/bin/java to your other JVM.

I use a several Java applications, some headless, some not on various linux
distros + Windows +MacOS. Over time, most apps have begun to provide their
own jvm. The others use various mechanisms such as setting JVM_HOME or
editing a shell script to allow user to choose a suitable JVM. I always
let the distro pick the "default" Java (e.g., openJDK), and install Oracle
Java when one of my apps needs something that doesn't work properly with
the distro package. It is an annoyance that apps use different, poorly
documented, mechanisms to control which JRE is used.

coexist in Fedora (use alternatives to select the one you want to be active)

The headless package (java-1.8.0-openjdk-headless) is a standalone
package intended to be used on headless servers where the user may not
want graphics related libraries installed.
The headless package is just a subpackage of the main OpenJDK build and
all it is is the full JRE minus some graphics related shared libraries
(which are then provided by the 'java-1.8.0-openjdk' package).
If you are using GUI apps, you just need to install 'java-1.8.0-openjdk'
and you will be able to run GUI apps. Apps distributed via Fedora should
have the proper dependencies (on headless vs full package); if you
notice that once does not, please open a bug against that package.

Deepak

When I installed Fedora Workstation, it loaded the headless JVM only. I installed the
full JVM, but installing libreoffice via dnf reverted back to the headless one. It's
almost like it considers the headless one to be the default.

Isn't the headless a dependency of the full one? As far as I know, headless
isn't a separate JVM install... it's just a partial install of the full
JVM, and installing the full one is basically just installing whatever was
missing from the headless one. Isn't this correct?

Yes, java-1.8.0-openjdk-headless is a requirement for java-1.8.0-openjdk.

From what I can see, java-1.8.0-openjdk only includes four shared
libraries, four icon (.png) files, a desktop file and the policy tool.
The rest of the payload comes from the headless RPM. There's quite a bit
of "alternatives" scriptlet magic that happens as well on the
headless RPM.

That is very strange. It would be useful to see the output of dnf when
you tried that. The headless package isn't a replacement for the full
one, it's the Java base. The full JVM package is just the parts that
have dependencies on graphical libraries and it has a dependency on the
headless package.

The headless and GUI enabled JVM package are not independent JVMs. The
GUI enabled JVM package just supplies some additional .so files; the
same JVM bits are used underneath.
The only way (I can see) it would revert back to headless is:
1. A bug in the JVM itself where GUI libraries are installed but it is
not seeing/loading them (we have never seen this before though)
2. A bug in dnf where it uninstalled the GUI enabled package due to some
weird conflict
Are you able to reproduce this issue, or do you still have access to the

I have the non-headless JVM installed now, and I haven't tried to replicate the issue
since.
Does dnf keep a log?
Here's my best recollection of the sequence of events:1. Clean install of Fedora 24 on
a new laptop.2. Java GUI app failed. Vendor tech support eventually identified the
headless JVM as the culprit.3. Installed Oracle JVM via rpm.4. Java GUI app worked.5.
Upgrade to Fedora 25, and Java GUI app still worked.6. Install libreoffice calc &
writer via dnf.7. Java GUI app failed. I checked and the only JVM installed was the
headless one.8. Install non-headless openjdk via dnf.9. Java GUI app works.

Your "Vendor tech support" should have just told you to do 'sudo dnf
install java'.
In Fedora 25, "java" is split across more than one package. Most
applications only need a partial installation, and that's what the
"-headless" package gives you. If you need the rest of "java", you
need to
install the extra bits you need.
$ sudo dnf install java # to install the full JRE
$ sudo dnf install java-sdk # to also install the JDK
If your "Java GUI app" was shipped as an RPM, it should have had a proper
dependency on 'java' or 'jre' and done the right thing during
installation.
If it wasn't an RPM, you just needed to ensure all of its dependencies were
installed first.
Did you also uninstall the "-headless" version when you installed the
Oracle JVM? That's the only thing I can think of which would account for
what you described. If that was the case, then you would have seen that
LibreOffice reinstalled the java-headless, because it is a dependency. When
that was reinstalled, it would have updated your "alternatives" priorities,
which apparently preferred the "-headless" version. Had you left the
"-headless" version installed, and simply updated the alternatives after
you installed Oracle JVM, this wouldn't have happened. Alternatively, had
you simply installed the full OpenJDK version which ships with Fedora 25 by
doing "sudo dnf install java", this wouldn't have happened.
Hope that helps explain what you experienced.

Tech support considered Java dependencies to be my problem. The app is just an executable
JAR.
I was unable to install the full Java via dnf, which is why I went with the Oracle rpm.
Pretty sure the rpm conflicted with the headless JVM, so I removed that one. I can't
explain this, user error is a likely possibility.
