Hi all, I have a question that I can not find an answer to... Recently I build for our servers a new hub, new world, keeping plugins sharp, check, check and check.... The weird thing is, the hub has the least plugins of all servers.... so this is a no brainer you would think, that's what I thought too. Before I changed the hub, the old one crashed when touching the console, and I did literally everything there to find the culprit. Now on our new hub, the same thing happens if I touch the console (I mean trying to type a command) and it crashes..... This is now what I get in the console: Code (Text): [09:29:34] [Server console handler/ERROR]: Caught previously unhandled exception : java.lang.NoClassDefFoundError: org/bukkit/craftbukkit/libs/jline/console/ConsoleReader$2 at org.bukkit.craftbukkit.libs.jline.console.ConsoleReader.readLine(ConsoleReader.java:2605) ~[spigot-1.17.1.jar:3180-Spigot-38e6c03-ca0fe5b] at net.minecraft.server.dedicated.DedicatedServer$1.run(DedicatedServer.java:130) ~[spigot-1.17.1.jar:3180-Spigot-38e6c03-ca0fe5b] Caused by: java.lang.ClassNotFoundException: org.bukkit.craftbukkit.libs.jline.console.ConsoleReader$2 at jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:636) ~[?:?] at jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:182) ~[?:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:519) ~[?:?] ... 2 more Plugins used are: LuckPerms, SonezSpawnJoin, DeluxeHub, BlockLocker, PlugMan, WorldBorder, Vault, SimplePortals, ProtocolLib, Statz, WorldEdit, WorldEditSUI, Essentials, Plan, EssentialsGeoIP Does anyone can explain why this only happens on our hub? and not on the other four servers??? On this new Hub I can exit this crash by clicking on the cross (X) on the top right of the console screen, it asks me then to stop the batch job, I can go from there on.... It still puzzles me.... Searches on internet even got me into the paper spigot area, but no answer there too..... Anyone?
