If you mean by "guarantee enum is not used" that I can decide wether the 
class is either 1.4 or 1.5 I fear that this is not possible. The only 
way I currently see is to have two different pipelines with lexer, 
filter, and parser for 1.4 and 1.5 and then parse the class first with 
1.5 and if errors occur use the 1.4 pipeline.
I haven't tried it yet but it seems feasible (and ugly :-( )

Thanks for your idea,
Joerg.
