String hashCode implementation in java 11 looks like this:

 public int hashCode() {
        int h = hash;
        if (h == 0 && value.length > 0) {
            hash = h = isLatin1() ? StringLatin1.hashCode(value)
                                  : StringUTF16.hashCode(value);
        }
        return h;
    }

Why do we need int h here ? Is it somehow related to thread synchronization ?
