Failed to load module "xapp-gtk3-module"

Apache NetBeans version

Apache NetBeans 13

What happened

During start-up Netbeans logged a message to the console. Since people probably usually start Netbeans as a gui they likely don't see console output.

Console output

 $ flatpak run org.apache.netbeans         -J-Dawt.useSystemAAFontSettings=on                   --jdkhome     /opt/lib/java/jdk/v17.00         --userdir     /home/william/.config/netbeans/v13.00/4ams/v17.00/user-00         --cachedir    /home/william/.cache/netbeans/v13.00/4ams/v17.00/cache-00

Gtk-Message: 09:35:57.337: Failed to load module "xapp-gtk3-module"

Please note this may be an effect of the flatpak packaging.

How to reproduce

Start netbeans flatpak from console.

$ flatpak run org.apache.netbeans -J-Dawt.useSystemAAFontSettings=on --jdkhome /opt/lib/java/jdk/v17.00

I would also start the normal binary install too.

Did this work correctly in an earlier version?

Anything else

the Netbeans option (presumably in the user/ directory) are set to "maximise native look and feel"
add fltpak to the drop-down list

this is most likely harmless. I have seen this before in other applications, a quick search resulted in: https://github.com/linuxmint/xapp/issues/134#issuecomment-817364455

The default Look and Feel is FlatLAF btw, the other selections are less tested - use on your own risk.

Some more information has bubbled up.

Netbeans fails to find a GTK libarary: libgtk3-nocsd.so.0
- This is found on this path natively: /usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0

However the flatpak seems to keep such things here:

$ ll ~/.var/app/org.apache.netbeans/.ld.so

The long hex number is a blob. hexdump yields the following a the top of the file:


$ hexdump  -C  ~/.var/app/org.apache.netbeans/.ld.so/87d15bf52ffceca6aac5ae3ca838aeb5ef0cb5581a1462f12ae8e6633b448870

  * Which is almost inscrutable.  One imagines this is ment to resolve to absent shared libraries
*  To me that suggests there is a packaging problem or versioning mismatch in the flatpak

At home I have a desktop PC with the same Ubuntu version, flatpak Netbeans installed, etc.  The flatpak Netbeans works on that PC.  I have removed and reinstalled Netbeans twice today.  Still getting that error.

On another tack, I thought I might use `flatseal` configure Netbeans so it can "see" that library locally.  Apparently flatseal doesn't work like that.

@aplatypus flatpak isn't listed in the dropdown because it's not produced by ASF. If you can reproduce the issue with the zip (or Linux installer or Snap package) then report here. If not, I suggest starting with https://github.com/flathub/org.apache.netbeans/issues
