This package has Build-Depends on GTK 2 (libgtk2.0-dev) and produces
binary packages with a Depends on GTK 2.

GTK 2 was superseded by GTK 3 in 2011 (see
<https://bugs.debian.org/947713>). It no longer receives any significant
upstream maintenance, and in particular does not get feature development
for new features like UI scaling on high-pixel-density displays (HiDPI)
and native Wayland support.

A porting guide is provided in the GTK 3 documentation:
https://developer.gnome.org/gtk3/stable/migrating.html

Thank you,

Jeremy Bícha dixit:

Yes, but this is not a problem for openjdk-8, which is also in the
boat of getting fixes only. It’s also not in testing, deliberately.

As there are no plans to remove Gtk+2, I’m downgrading this.

I was surprised to learn this morning that openjdk-8 upstream has ported
to GTK3 (some time ago actually):

https://bugs.openjdk.org/browse/JDK-8207322
https://github.com/openjdk/jdk8u-dev/commit/4ea4c29a4ca3d984fb28b054340d618ac5f2009a

On my system (which has libgtk2 installed), testing an openjdk GUI
application shows that gtk3 is loaded at runtime when it is available:

$ export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
$ $JAVA_HOME/bin/java -jar /usr/share/wadc/wadc.jar &
$ grep gtk "/proc/$(pidof java)/maps"

For that test, I used trixie's wadc and sid's openjdk-8-jre.

Possibly it would load gtk2 if 3 was not available. I haven't read
through the patch, although the JBS bug references "failing forward" to
GTK3. In any case, I think the Depends: on libgtk2 is no longer correct.

We believe that the bug you reported is fixed in the latest version of
openjdk-8, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1121358@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Closes: 1121358
Changes:
 openjdk-8 (8u504-ga-1) unstable; urgency=medium
 .
   [ Emilio Pozuelo Monfort ]
   * Set a concurrency limit for the tests to avoid the build being
     killed due to OOM.
 .
   [ Vladimir Petko ]
   * d/rules: Check DEB_BUILD_PROFILES in addition to DEB_BUILD_OPTIONS
     to set up with_check variable, but regenerate/check debian/control
     only on amd64 when with_check=yes and DEB_BUILD_OPTIONS ∌ nogen
 .
   [ Thorsten Glaser ]
   * Imply gen-autopkgtests when running d/rules d/control,
     to make sure everything is updated (also makes it phony)
   * Lower concurrency limit: use just one for lowest-spec machines
   * New upstream release
     - CVEs and other notes are not yet published but should
       be on <https://bit.ly/openjdk8u504> later
   * Update GCC to release mapping
   * Use Gtk+3 over Gtk+2 for forky/sid and stonking (Closes: #1121358)
   * debian/buildwatch.sh: use on more slower architectures
   * Derivatives: fix ppa_build detection
   * Remove CONFIGURE_ARGS, which were long unused and no longer work
   * Bump Policy
   * Retire powerpcspe as it troubles lintian and is distant memory
   * Drop lintian overrides it no longer knows
