Answer 2

First off, this is not a definitive answer. A few years ago, the answer would have been a resounding no and a redirection to GWT or similar things.

That said, compiling to web assembly may be possible. It was not possible because of a lack of garbage collection in web assembly. Since adding garbage collection to web assembly was a stated goal, compiling Java to web assembly should be possible or will be possible in the near future.

JavaScript programs can call web assembly libraries very easily.
