Cooja crashing all the time

[NestorESA]

I am simulating a network with one root, sometimes 2 and several nodes, it uses TSCH and RPL, most of the times whenever I pause and unpaused the simulation, cooja crashes and always the say message:
Task :run FAILED

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':run'.
Process 'command '/home/user/.gradle/jdks/adoptium-17-x64-hotspot-linux/jdk-17.0.5+8/bin/java'' finished with non-zero exit value 134

I have more than 50 error report files, one from each crash, I tried finding solution online but couldn't find something useful.
I am not using it in dockers, and I run cooja using ./gradlew run

The part of the error message included is just Gradle detecting that something went wrong, it doesn't show anything technical.

What are the first 5 lines of git show from the directory where you use ./gradlew run?

Could you try to reproduce the problem inside the Docker container?

There were quite a few fixes relating to GUI drawing correctness in 4.9, does this issue still happen for you?
