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?
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._______________________________________________On Tuesday, January 3, 2017 10:07 AM, Deepak Bhole <dbhole@redhat.com> wrote:

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?
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.
