Task :run FAILED (rc 134) on Fedora 35, KDE, x11

[bogdandragoiu]

Hello,

First off, the daemon works really well! Thank you for making it!

I am experiencing a similar issue to #9, I tried installing similarly to how you did in the comment but no success.

• The communication to the daemon seems to run, but then OpenJDK seems to crash.
• I tried installing and reinstalling the dependencies with no success (see screenshot).
• Disabling SElinux also did not help.
• In hs_err_pid* I also get a few java/lang/NoSuchMethodError which I'm not sure are the cause of OpenJDK crashing.

I've attached the latest error message, a screenshot and hs_err_pid* log.

Starting a Gradle Daemon (subsequent builds will be faster)

I also just tried using the older versions of JDK which worked in your VM and same effect:

wget https://kojipkgs.fedoraproject.org//packages/java-11-openjdk/11.0.14.0.9/2.fc35/x86_64/java-11-openjdk-11.0.14.0.9-2.fc35.x86_64.rpm

sudo dnf install ./java-11-openjdk-11.0.14.0.9-2.fc35.x86_64.rpm java-11-openjdk-headless-11.0.14.0.9-2.fc35.x86_64.rpm

I did some further testing in a VM and found that Fedora KDE spin is affected with either the newest or specific java-11-openjdk issue you tested in #9.
Fedora with Gnome and wayland does work.

[kurikaesu]

Thanks for the report!

With the KDE spin VM you ran did you try rebooting after installation before running?
I have seen the exact same terminal corruption happen before but it only happens when trying to run the driver immediately after installation. A reboot appears to fix the issue.

Let me know if rebooting also fixes it for you.

[bogdandragoiu]

I tried it with no success. I think my KVM setup might be weird or the USB attachment is not working since I can see the same device in both guest and host. I'll try to see if I can reproduce with VirtualBox the way you did and report back.

I didn't think much about the corruption since it showed up when I interacted with the tablet. My suspicion is more something in openjdk or libraries that get called by it is crashing before the GUI is drawn and somehow it works in default Fedora with Gnome, but not the KDE spin.
My initial suspicion was on my system having open glibc with 32 and 64bit and a default Fedora install only has the 64bit, but I couldn't prove that. I did compare versions of those libraries between the Fedora flavors and they seem identical though.

[kurikaesu]

Sorry for the late reply, I am currently in between housing and don't have a proper setup to test/debug. I'll have to try on my end with Fedora and KDE spin to see if I can work out why it doesn't run.

[bogdandragoiu]

Still have not found the issue. I've upgrade to Fedora 36 since, but the issue persist. Same with a secondary physical machine.
Have tried multiple java-11-openjdk RPMs and also tried one I downloaded outside of the repos and same issue.
I'll keep digging.

[bogdandragoiu]

Tested some more and found that on a working Fedora 36 with Gnome it works. I added KDE via sudo dnf groupinstall "KDE Plasma Workspaces" then rebooted an logging in with KDE reproduces the error. Logging back to Gnome and the GUI works again.

[bogdandragoiu]

I think I found the culprit. Just messing around I commented out the following:

class UserlandUtility : App(UserlandUtilityView::class){
    override fun onBeforeShow(view: UIComponent) {
        try {
            // GlobalScreen.registerNativeHook()
        } catch (ex: NativeHookException) {
            println("Could not initiate global hook")
        }
    }

And the GUI showed up! But shortcuts can't be set which makes sense considering what com.github.kwhat.jnativehook is for.

[kurikaesu]

Thanks for digging into this. I'll have a look at the native hook library and see if they have changed things up in the latest versions or if the latest version is not compatible with that version of Gnome.

Will have to wait until I finish getting set up here at my new place which should be after this Wednesday the 18th.

[kurikaesu]

I've dug into this more on my side and can confirm that on a fresh install of the KDE spin version of Fedora, the GUI will not launch correctly, crashing because of jnativehook.

The version of Fedora that I had installed is 36.

This version of Fedora installs OpenJDK 17 by default and that seems to have issues with jnativehook even though jnativehook says it supports 17.

Installing openjdk-11 by doing a:
sudo yum install java-11-openjdk

Then switching the default JDK the system uses to 11 instead of 17 by doing:
sudo alternatives --config java and picking number 2 (for me since number 2 was version 11

Running ./gradlew run succeeds correctly with no crashes and the GUI is able to communicate with the daemon fine.

At some point we may need to dig into why jnativehook crashes on JDK 17 but that may be something to raise an issue on the jnativehook repo instead of here.

Hope that helps!
