Altair AI Studio/RapidMiner: Visualizations not working

Hi, I am using Altair AI Studio aka RapidMiner version 2026.1.1 from AUR and if I run some process and click Results -> Visualizations no plot appears. Instead, I get the following error messege in GUI: "Could not initialize HTML5 browser!"

And the relevant part of logs:

So I gather it is either some issue with JXBrowser, or something with integrity checking...

The path:

/opt/altair-ai-studio/bin/jxBrowser8.12.0-Linux64/

exists and is world-readable and is populated with what seems the expected content.

The jxbrowser.jar is not part of the package, so I cannot verify that letting the software to unpack it produces  the content that passes integrity check.

The following Javas are installed (and the default is set as per the AUR's package instructions):

# archlinux-java status
Available Java environments:
  java-11-openjdk
  java-17-openjdk (default)
  java-21-openjdk
  java-8-openjdk

The issue persits with java-8 being the default, and is also present on another Arch machine.

Any ideas?

Re: Altair AI Studio/RapidMiner: Visualizations not working

https://community.altair.com/discussion … l5-browser suggests it may have to do with chromium processes that are blocked .

Do you have chrome/chromium running ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Altair AI Studio/RapidMiner: Visualizations not working

Chrome is not installed, Chromium is installed, but not running.
