GSON not working

[mowmowkittycat]

Expected behavior

GSON should work because it is bundled with Bukkit, but it just gives me errors

The version of gson bundled in the server is outdated, your class is designed in a way which this basically breaks, we basically need to look if it's safe to update gson (do they follow semver? er)

Just tested on latest paper version, It gives same error.

Just tested on latest paper version, It gives same error.

That's why it was just a comment on the fact that you checked a box saying something clearly not true, not a solution to your issue. See electronicboy's comment

[mowmowkittycat]

semver? er

yea, they follow semver.
Latest version is 2.8.7
