Thanks, AC.
It works fine. The warning about the empty token sequence disappeard.

Now I have to solve a lookahead warning because, even if I followed,
within Factor(), the suggestion

3.3. What if more than one regular expression matches a prefix of the
remaining input?

ID and GROUP_ID share a common prefix and cause a lookahead problem.
But this is another story and I began to study the lookagead tutorial
https://javacc.dev.java.net/doc/lookahead.html


Noch einmahl, vielen Danke. :)
Have a nice week end!
