Bug description

Just downloaded Paper 1.16.5 Build 778 running Java 16

Steps to reproduce

Download a copy of Paper 1.16.5, run it in localhost
Download a copy of EssentialsX 2.18.2, placed it on Plugins folder

Expected behaviour

Everything should run normally without an error

Actual behaviour

There as a huge spammed error

Your items.Json file is corrupt

Yeah, and that doesn't help me since the JSON corruption lies at the start of EssentialsX I haven't changed nor touched anything literally just put the file inside the plugins folder.

Tried deleting the JSON file but still persist

Your items.Json file is corrupt

Cannot replicate on a fresh download of Paper 1.16.5 build 778 and EssentialsX 2.18.2.

Could you run java -version in a command prompt (you appear to be on Windows) and post the output?

In addition, could you try the following:

• Stop your server
• Delete both the EssentialsX jar and the items.json file
• Redownload EssentialsX from the website
• Restart your server

I did what you've said and I'm still having the error however, after adding Vault and LuckPerms the problem goes away, I guess for now it can be fixed? I'll try experimenting for more incase I'll try compiling and create about it.

Unable to replicate on my end either, using the exact same JVM version, Paper version, and EssentialsX version. The error printed also comes from the Gson library while parsing itemdb. The only thing I can think of is that either your items.json file is invalid, or perhaps you have a corrupt EssentialsX or Paper jar (in which case redownloading may help).

Will close this issue for now but if you do find further information which shows this to be a bug we can re-open it.
