Hello Thomas,

I have installed DW v6.5.4 in NFS file system at /datawarrior/6.5.4/ directory path on Linux Rocky 9.8. There is no error during running of buildDataWarrior script and the datawarrior_all.jar is created at /datawarrior/6.5.4/ but when I'm running it using runDataWarrior script, it is giving below error. I want to clarify that I don't have internet access where installation is done and I also don't have root access. I can do the installation at specific path only. Can you please help me with this?

Compiled with below Java version which is installed on server.
openjdk version "21.0.5" 2024-10-15 LTS
OpenJDK Runtime Environment (Red_Hat-21.0.5.0.11-1) (build 21.0.5+11-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-21.0.5.0.11-1) (build 21.0.5+11-LTS, mixed mode, sharing)

javac 21.0.5

Regards
Akash
