Is this a bug : Exception in thread "main" com.google.gson.JsonIOException: Failed making field 'java.time.ZoneRegion#id' accessible; either change its visibility or write a custom TypeAdapter for its declaring type ?

Is this a bug, or my env need more config to make it work? Thank you

Because on Windows, I don't have this problem

So is this mean it's a bug?

#1944

Is there any possibility to run on java 17 with any flags? seems it's now... forced?

[SimonLammer]

Any update? I'm running into this on openjdk 21.0.2

[ckcherry23]

Based on #2025 (comment), we may have issues with the gson package from JDK 17 onwards, so for now we recommend using Java 11 to run RepoSense.
