Description
2905                for (int i = 1; i < subtags.length; i++) {
2906                    if (isSubtagIllFormed(subtags[i], false)) {
2907                        isIllFormed = true;
2908                    }
2909                    break;
2910                }

Since the loop increment i++; is unreachable, the loop body will never execute more than once.
Comments
The break statement should be put just after "isIllFormed = true;".
