Allowing multiple threads direct access to UI state causes a lot of
pain (every data structure needs to be synchronized, lots of
opportunities for races and funky timing issues). You really want the
UI to be single-threaded.

"Greatly discourages sharing" seems like a bit of an over-statement.
The Java programming language provides well-defined methods of sharing
data between threads, and the Java memory model rigorously defines
what is and isn't expected to work. (Or were you referring to
something else?)
