Indeed.  ANTLR knows that the plus is supposed to be part of an 
expression and when nothing good follows it it throws an exception 
(check the generated code).  Perhaps you should define an exception 
handler in your expression rule that catches the exception and swallows 
it so that the good part of the expression is preserved.

This is certainly a task that ANTLR is not designed for.
