[antlr-interest] Lexer exception?

[Jens Bartelheimer]

Hi Martin,

thanks for your reply but if I turn off the option there are no 
additional exceptions.

If I turn it on explicit I have the following error in the Lexer:

My error message:
The method recover(RecognitionException, BitSet) is undefined for the 
type UMLLexer

Why? Is there a mistake in my Lexer?

Jens
