Actually it is a public class and in the same package as the parser.

After having read some things about reflection I thought it should work
but didn't.

Now I've set it up with ASTLabeType="ASTWithOffsetInfos" as a parser
option. And in order not to get some cast errors I had to set the node
class type manually for the AST factory with:
astFactory.setASTNodeClass(ASTWithOffsetInfos.class);

Shouldn't that be set along with the ASTLabelType option? Or has that
something to do with the fact that one wants to be able to generate
heterogenous trees?

Thanks Xue Yong Zhi for the help.
