mbien opened a new pull request, #9004:
URL: https://github.com/apache/netbeans/pull/9004
first commit is the fix, second is just cleanup
- only run x11 workarounds when x11 toolkit is active
- wakefield may use WLToolkit on wayland (`-Dawt.toolkit.name=WLToolkit`)
The `#183739` might be still useful, unfortunately I don't know what
`#198639` does since bugzilla isn't loading the issue for me.
symptom: startup failure

I don't think project wakefield has made builds available yet, so to test
this (linux+wayland) it would require the following:
```
git clone -b jdk25-wayland --single-branch --depth 5
https://github.com/openjdk/wakefield.git
cd wakefield
bash configure --with-vulkan
make images
```
start nb using the wakefield JDK with the following flags:
```
-J-Dawt.toolkit.name=WLToolkit -J-Dsun.java2d.vulkan=True
```
you should see something like this in the log instead of the exception:
```
Vulkan rendering enabled: YES
Presentation enabled: YES
Accelerated surface data enabled: YES
Devices:
*0: NVIDIA GeForce GTX 1080
```
Doesn't look great on my system though. Something is wrong with the font AA,
popups are all over the place and some overlays (e.g editor highlighting layer)
doesn't work. It runs at least.
thanks to @cstamas for noticing this.
