The old discussion was related not only to the comment but to the invalidateCurrentContext, do we need to do it?

src/java.desktop/macosx/native/libawt_lwawt/java2d/metal/MTLGraphicsConfig.m line 152:

Please also check how this function is called, looks like previously it was called as a selector+an array as a parameter, and then reworked as a performOnMainThreadWaiting+block, but it still use an array as a parameter. I think it is similar to JDK-8238075.
