Basically, in JavacParser, UNDERSCORE case havent been present in block parsing switch statement, so it was treated as default and it wasnt recognized as part of yield statement. This simple fix adds UNDERSCORE case right next to IDENTIFIER case to solve this problem. Syntax like yield _ = 3 is still invalid.

Looks good to me, thanks!
