WARNING: Illegal reflective access by org.yaml.snakeyaml.introspector.PropertyUtils (file:/C:/Servers/bungee/BungeeCord.jar

I am running java 10 and got this error:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.yaml.snakeyaml.introspector.PropertyUtils (file:/C:/Servers/bungee/BungeeCord.jar) to method java.beans.FeatureDescriptor.isTransient()
WARNING: Please consider reporting this to the maintainers of org.yaml.snakeyaml.introspector.PropertyUtils
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

It's a warning in a third party library we use.
Bungee cannot fix it (and it doesn't affect anything)

This is fixed in SnakeYAML 1.20 and later

Almost guaranteed it will just be replaced by another warning, but SnakeYaml needed an updated anyway
