Can ANTLR generate a parser class that is final?

I'm using ANTLR 3.1 and ANTLRWorks to generate a parser class in Java. The parser performs better if I mark the generated class with the Java final keyword. The problem is: I am adding this keyword manually after each time I re-generated the code from the ANTLR grammar. Is there anyway, in the grammar, of telling ANTLR to add the final keyword to the generated parser class definition?

From this thread (oops- my bad), it looks like it's not possible to do it yet. :(

What version of Java are you using? The more recent ones should detect leaf classes automatically, as should any since 1.3 in -server mode.
