Fluent method is not exact replica of setter method

[fjtirado]

If the generated setXX method is not trivial, his withXXX counterpart wont be aligned.
For example

@OneOfSetter(String.class)
    public void setExpressionErrorDetails(String expressionErrorDetails) {
        this.value = expressionErrorDetails;
        if (expressionErrorDetails_Pattern.matcher(expressionErrorDetails).matches()) {
            this.expressionErrorDetails = expressionErrorDetails;
        } else {
            if (literalErrorDetails_Pattern.matcher(expressionErrorDetails).matches()) {
                this.literalErrorDetails = expressionErrorDetails;
            } else {
                throw new ConstraintViolationException(String.format("%s does not match any pattern", expressionErrorDetails), null);
            }
        }
    }

is quite different from

public ErrorDetails withExpressionErrorDetails(String value) {
        expressionErrorDetails = value;
        this.value = value;
        return this;
    }

To fix that, withXXX should call setXXX
