Fix for Traccar QPKG startup issue on QNAP (UnsupportedClassVersionError / QJDK21)
If your updated Traccar QPKG fails to start or gets stuck on the loading spinner (port 8082), the issue is a Java version mismatch.
The Problem:
The new Traccar version requires Java 21 (class file version 65.0), but the QPKG startup script is hardcoded to use Java 18 (QJDK18). You will see this in the logs:
“java.lang.UnsupportedClassVersionError: org/traccar/Main has been compiled by a more recent version of the Java Runtime”
How to fix it:
1. Install QJDK21 on your QNAP (via App Center or MyQNAP).
2. Log in via SSH and run this command to automatically update the startup script from QJDK18 to QJDK21:
sed -i ‘s/QJDK18/QJDK21/g’ /etc/init.d/traccar.sh
3. Restart the service:
/etc/init.d/traccar.sh restart
You can monitor the live boot log using:
tail -f /share/CACHEDEV1_DATA/.qpkg/traccar/logs/tracker-server.log
