Error in Expressions.PathStyleExpression#getValue

Expressions.PathStyleExpression#getValue:

@Override
public String getValue() {
    if (this.getPattern() != null) {
        // this line
        return "{" + this.separator + this.getName() + ":" + this.getName() + "}";
    }
    return "{" + this.separator + this.getName() + "}";
}

Maybe the intentions is:

return "{" + this.separator + this.getName() + ":" + this.getPattern() + "}";

?
