I think this should compile. "It's just a protected member." The ticket says it compiles if everything is in a single package.

But Scala 2.13 also refuses this one. Is that a known bug?

I see Scala 3 has a different definition of protected. It disalllows access to protected Java members from traits
illegal access to protected method test in class Base from trait Ext
Maybe Scala just makes everything public if it wants to do something like that.

The Scala 3 ticket was noticed at scala/bug#12249 which is just Scala classes. The other link is a Java base class with protected member. I haven't reflected deeply yet.

I am not sure about it either. But at least we don't crash anymore, and do the same thing as Scala 2.13 does.
Fixes #11170
