#184988 Hello there.

So, I recently downgraded my (working and running) 1.10.2 Pixelmon Server to MC Version 1.8.9, however, I have used the same method as when I installed the previous Server (And to double-check I have installed the 1.8.9 a bunch of times, before re-installing the 1.10.2 version again to see if it worked, which it did) and whenever I drag and drop Pixelmon 1.8.9 into the mods folder the Server just refuses to start.

I am using Nitrado on this one, but it does work with 1.10.2 so the issue is with the MOD itself, isn't it?

This is part of the LIVE-Console Nitrado offered after I threw Pixelmon on there and restarted the Server:

There seem to be quite a few Java errors but 1) Why would it have Java Errors with 1.8.9, but not with 1.10.2 and 2) How do I fix those, since the server uses Nitrado's provided Java?
Oh and 3) You guys see anything else that needs fixing here?

#185044 You need to tell your server host they need to update to a supported Java, the reason you can start 1.10.2 is due to the removal of our Java 8 checker but it would surely crash at some point due to us utilising Java 8 functions
