I have the following java code:

final int sub;
if (text.length() > 1 && text.charAt(1) == ' ') {
    sub = 2;
} else {
    sub = 1;
}

and for the second line if (text.length() > 1 && text.charAt(1) == ' ') { I get the following exception:

[INFO] PMD: eo-parser/src/main/java/org/eolang/parser/XeEoListener.java[1127-1127]: Use String.isEmpty() when checking for empty string (UseStringIsEmptyRule)

But I don't check for string emptiness here.
