Injector Fail

[RHydrix]

latest.log

I removed all plugins except for worldedit version 7.2.5, and AsyncWorldEdit 3.8.3

Server is on Paper Spigot 1.16.5 version 686 any ideas?

[Black-Hole]

Spigot changed the plugin class loader recently. I think it's caused by that.

Same on
Paper version git-Paper-693 (MC: 1.16.5) (Implementing API version 1.16.5-R0.1-SNAPSHOT)
WorldEdit version 7.2.5+57d5ac9
AsyncWorldEdit version 3.8.3

Looks like a problem caused by change in Spigot:

Sorry for mixing topics - #377 (comment)

Did you have a link to this 3 week old working WE on Java 16 working with the temp AWE hack?

Thanks :)

[SBPrime]

Sorry I removed that JAR when I started diagnosing the issue.

That said, I managed to add a fix to the plugin (not the best piece of code but still does its job ;) ).

I will push a release within next 48h, I still need to do proper tests on this. You can ask on the forum, perhaps someone can help you.
