[antlr-interest] internal error: NFAToDFAConverter.getPredicatesPerNonDeterministicAlt(NFAToDFAConverter.java:1604): no AST/token for nonepsilon target w/o predicate

[Sebastian R. Wain]

Hi,

I am using the latest version of ANTLR, but processing my grammar I 
receive multiple:
    "error(10):  internal error: 
org.antlr.analysis.NFAToDFAConverter.getPredicatesPerNonDeterministicAlt(NFAToDFAConverter.java:1604): 
no AST/token for nonepsilon target w/o predicate"

How can I solve this issue? Do I need to move to a previous ANTLR version?

Thanks,
Sebastian
