Re: OS/X Java native bug

Your comments don’t make sense to me.

You either post an event to run the code on the main thread or, if you are on 
the main thread, you run the code directly.

Running the code directly is what invoking a block does.

How is that unnecessary?

Would it make more sense if the parameter were named “c” and the code said 
“c()”?

There is a situation where I think it is fine to use the implementation 
details, and that is to work around a problem in an old release of macOS, which 
is never going to be changed (with the possible exception of a security patch, 
I suppose, but that is unlikely to cause any problems).

Believe it or not, some bugs are not fixed until the next release, or the one 
after that, or …
