Adding this jvm flag could help: --add-opens java.base/java.lang=ALL-UNNAMED

GriffinCodes commented 3 years ago

It does, but that seems like a workaround, rather than a fix? Every server owner would need to add that flag for the plugin to work

bergerkiller commented 3 years ago

Yup. Blame oracle.

bergerkiller commented 3 years ago

I'm trying to see if there's something I can do on my end, as there is a way out with the MethodHandles API.

bergerkiller commented 3 years ago

This problem should be fixed, hopefully. Let me know if there are any other moments where this error pops up. https://github.com/bergerhealer/Mountiplex/commit/d05c9fb4983618154b323534440cb4430f79ccc2
