With the upgrade to Snakeyaml 1.32, there is now a default size limit of ~3mb: https://bitbucket.org/snakeyaml/snakeyaml/commits/440d98e2ebd586aafd9034fc74a2a47c656eb0ce
There are some plugins that use Bukkit's configuration API for storing plugin data that can exceed this new default limit. It might make sense to increase or even remove the default limit inside Bukkit (the previous limit was 100mb).
Error:
org.bukkit.configuration.InvalidConfigurationException: org.yaml.snakeyaml.error.YAMLException: The incoming YAML document exceeds the limit: 3145728 code points.
Other alternatives could be to:
- Rollback the upgrade.
- Expose the file size setting to plugins.
But I think increasing the default limit will probably suffice.
