src/core/org/luaj/vm2/lib/CoroutineLib.java:

Internal classes create, resume, ..., yield, wrap renamed Create, Resume, ... Yield, Wrap

This change was motivated by the fact that yield is a restricted name in JDK 14+

A lowercase 'yield' class was producing a warning in JDK 8 and could potentially not compile in newer JDK.
