Evaluation seems to be too slow

[hoechp]

I did some evaluation and didn't get an error, but like already at the second regular expression, it didn't run through, because the boolean java.lang.String.matches(String regex) didn't terminate in any reasonable time. It just seems that it isn't made for such long regular expressions.

My expressions may have some unnecessary parentheses, but that can't be the reason why it's so slow. If the results were wrong, it would just give negative results, though. I don't exactly know what's going on here.
