Console is frequently being spammed by these errors:

ClassNotFoundException has nothing to do with pmmp. That's a plugin error. Just read the error and fix it / stop using that plugin.
@Muqsit Pmmp could get a ClassNotFoundException anytime just as a plugin could. The question is if a plugin caused this, or PMMP did. This is not a master branch and nothing is guaranteed to work.
This specific error appears to be due to the namespace change. This is plugin caused because all PMMP namespaces are up-to-date
This is an issue with an incompatible plugin. This is exactly why you shouldn't just "bump the API" or "compatible=true" hack.
