Antlr 2.7.7 is a dependency of Antlr up to version 3.3 (odd, yes, I know). It seems they removed this dependency on Antlr 3.4. We will upgrade it for the next release (Drools 5.4).

I notice that the Drools 5.3.0 distribution packages antlr-runtime-3.3.jar,
antlr-3.3.jar & antlr-2.7.7.jar.

Is there a reason why antlr 3.4 can't be used? Also, why are both 3.3 &
2.7.7 included?

Any input is appreciated.
