So, I have a particle API in my plugin that uses some reflections. Don't worry, that's not the main topic, even I don't understand reflection totally.
I have an 1.20.4 test server using jdk 22, and an 1.20.6 test server using the same JDK.
My plugin works from 1.8 to 1.20.4.
On 1.20.6, I have this issue:
Here is the line of code referenced by the error, the first "static final Class<?>" is the 18th line, the one referenced by the error
Does someone knows why a line like this would cause this weird error in this specific minecraft version? This doesn't occurs on spigot

Here is the line of code referenced by the error, the first "static final Class<?>" is the 18th line, the one referenced by the error
Java:
static final Class<?> BLOCK_DATA_CLASS = FastReflection.optionalClass("org.bukkit.block.data.BlockData").orElse(null);
static final Class<?> DUST_OPTIONS_CLASS = FastReflection.optionalClass("org.bukkit.Particle$DustOptions").orElse(null);

static final Map<Class<?>, Class<?>> DATA_ADAPTERS = new HashMap<>();
static final boolean LEGACY = !FastReflection.optionalClass("org.bukkit.Particle").isPresent();
Does someone knows why a line like this would cause this weird error in this specific minecraft version? This doesn't occurs on spigot
