Description
We'd like to track state changes in our parser. The objective is to compute an estimate of how much of the language is covered by the examples we have. We've tried with a listener but it's not enough to track just rule enter/exit.
However, the setState method is final (in the Java target) and the parser does not notify anyone of its state changes.

Research direction
Start by locating the Java target's final setState method and the parser notification path. Determine how state changes could be exposed beyond rule enter/exit; done means a listener can observe those changes well enough to estimate language coverage from examples.
