Jaamsim keeps crashing on Ubuntu 24.04. The cause is not in Jaamsim but in Mesa Freedesktop (in particular it crashes in latest libgallium-26.0.0-devel.so). Is anyone using Jaamsim on Linux/Ubuntu?

As Harvey mentioned in the post (https://groups.google.com/g/jaamsim-users/c/sLGVl47plO4), JaamSim only started running on my Ubuntu 24 after I installed all three versions of the open-source JDK (17, 21, and 25).

If you've already got all three versions of java installed on your
machine, could you try running the latest jaamsim version with each
version and let me know which ones are successful and which are
unsuccessful?

At your request I've ran the latest JaamSim with all openjdk versions (17, 21, 25). All crash on Mesa's libgallium (latest mesa 26.0.0-devel). This is the script I'm running:
```
#!/bin/bash

I can send you the (rather verbose) java log files if you need them.
Thanks for your help!

It would be more interesting (but likely not any different) with the
following (remove all the other workaround pieces, I'd rather have the
raw errors from the default way of running it).
$JAVA_HOME/bin/java
-XX:ErrorFile=$logfile \
-jar jaamsim/build/jars/JaamSim2025-09.jar
The enable native access flag should not be needed at all as that was
the purpose of the 2025-09 release. You can send me the error files
directly, I anticipate they are failing in the same way, but let's
find out!
Cheers

OK, running (as you said) with script:
```
java_version=17

$JAVA_HOME/bin/java \

I use Linux (currently Debian 13) and I use JaamSim on it.
I use the openjdk 25.0.1 2025-10-21
I am running it with this command:
java --enable-native-access=ALL-UNNAMED -Djava.util.concurrent.ForkJoinPool.common.parallelism=1 -Djava.awt.robot.singleThread=true -XX:ActiveProcessorCount=1 -jar JaamSim2025-09.jar

Jaamsim keeps crashing on Ubuntu 24.04. The cause is not in Jaamsim but in Mesa Freedesktop (in particular it crashes in latest libgallium-26.0.0-devel.so). Is anyone using Jaamsim on Linux/Ubuntu?

I tried opening an example running with java-25 and your args:

Still crashes on `libgallium`

I have filed a bug report with Mesa3D.
If anyone has success running JaamSim on an Ubuntu 24.04.3 machine, please let me know!

Have you ever run another version of Linux?

>> Have you ever run another version of Linux?
For work I have to stay with LTS; installing an rpm-based Linux version just for trying out, is a bit much ... (I won't switch to rpm anyway).
As said, I have filed a bug report with Mesa3D and told them they can run JaamSim on Ubuntu 24.04.3 and see for themselves where `libgallium` crashes (which it does even with their latest 26.0.0-devel version).

There is progress but no resolution yet. This is the current situation: https://gitlab.freedesktop.org/mesa/mesa/-/issues/14246#note_3186910
The Mesa dev team suspects there may be some kind of buffer overrun, or race condition going on...
As said, with latest Mesa3D dev branch (26.0.0-devel) and LIBGL_ALWAYS_SOFTWARE=1 things are better, but still unstable.

The Mesa developers think this may be the cause of Jaamsim crashing (https://gitlab.freedesktop.org/mesa/mesa/-/issues/14246#note_3190454) on Ubuntu 24.04.3 (notice it crashes even at some point when switching workspaces; that is with a Jaamsim model loaded, but without any Jaamsim interaction, just switching workspace):
"""
The crash happens in Mesa. My concern is that the app might be doing unsafe threading and/or memory handling with its OpenGL calls. Given its a java app tracking this down is a little harder, for example we can't make use of valgrinds memtool to easily find memory issues. The rendering code is here https://github.com/jaamsim/jaamsim/tree/master/src/main/java/com/jaamsim/render if someone has the time to investigated properly.

I can confirm that JaamSim runs perfectly on Ubuntu 24.04.3 on an (older) Dell Precision M6800 (Intel CPU) with Intel Haswell GT2 integrated GPU (hsw gt2). Therefore, the problem is likely Mesa3D's troublesome support for AMD's integrated Radeon GPU.

FYI:
JaamSim runs fine on AMD machine with Ubuntu 24.04.3 when all graphics is handled by NVIDIA RTX 3060 GPU (this requires the following environment varialbles to be set:
__GLX_VENDOR_LIBRARY_NAME=nvidia
__NV_PRIME_RENDER_OFFLOAD=1
).
Again, this supports the suspicion that Mesa3D doesn't support AMD's inbuilt Radeon Graphics properly.

Dear JaamSim dev team:
FYI: Mesa dev says that "Unfortunately no the JaamSim team did not correctly identify the problem."
Now that I'm offloading the JaamSim graphics to an NVIDIA RTX 3060 card (it needed some envvars set), it works smashingly (no crashing).
Thanks for the great simulation tool!
(I'm happy to help with further testing on AMD Radeon hardware if needed.)
