Using Latest Spigot version, protocolLib 4.4.0 and tried also #422 from Jenkins. It is giving same errors.

Follow this template except for feature requests. Use pastebin when providing /protocol dump and any relevant errors.

Make sure you've done the following:

• [checked ] You're using the latest build for your server version
• [not sure] This isn't an issue caused by another plugin
• [yes, multiple times ] You've checked for duplicate issues
• [no ] You didn't use /reload
