Your Expectation

When launching a rocket the galaxy map should display planets and moons.

The Reality

After the map opens I get this:

and this when selecting a planet from the menu:

Tested this on my server but also in a local world on a completely vanilla Java 21 install from the GTNH download site.

Your Proposal

Not sure what's happening here

[lynxx131]

Yeah the camera is still moving along it's orbit just no planet or moon.

Ah this appears to be a GraalVM related issue, switching to Adoptium JDK 21 resolved the issue so all good.

I was running graalvm-ee-java17-22.3.5, I don't know the dev team's stance on GraalVM so feel free to close this issue if it's not "officially" supported.

For reference I was running with the following GraalVM args -Dgraal.LoopRotation=true -Dgraal.PartialUnroll=true -Dgraal.VectorizeSIMD=true -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1

So if I remove -Dgraal.VectorizeSIMD=true then the map view works again.

Not sure if this is something that can be fixed or whether it's just a weird behaviour with Graal and GTNH.

If it's just an incompatibility it could be worth noting it down somewhere for future reference.
