Bug description

When running "/sudo (target player) c:(insert message here)" both the command sender and the target player get kicked for "Chat message validation failure"

Steps to reproduce

Install latest build of Essentials.
Put two accounts on your server
Run the command /sudo (other player) c:(insert message here)

Expected behaviour

Other player should say whatever message you put after c: without error.

Actual behaviour

Both your account and the other player's account get kicked for "Chat message validation failure"

Try with the latest dev build. This is probably a duplicate of #5031 which is fixed in the latest dev builds (#5030). Read mdcfe's comment below

I tried with the latest dev build (2.19.5-dev+40-422f25a), issue still occurs.

This is not a duplicate of #5031. It is most likely due to an implementation choice by Spigot regarding the chat method we call that will need either changing upstream or working around in EssentialsX.

Fixed as of Paper #116
