Are you going to update the java?

I think I should warn you.

Are you going to update the java? Look:

[16:34:04] [Server thread/WARN]: [BedWars] Future versions of plugins from ScreamingSandals will require at least Java 11. Your server is not prepared for it. Update your Java or contact your hosting.Java 8 for commercial usage is already out of casual support, for personal usage it's supported until December 2020!Java 9 and Java 10 were short-term support versions, these versions are already not supported.

[16:34:04] [Server thread/WARN]: [BedWars] Future versions of Java will require Minecraft version at least 1.12

I contacted the plugin developer and he answered that.

Spigot 1.12.2

Warning, as I said before in this post:

Are you going to update the java?
