TYPO3 Core

Furthermore: Every VH in ExtensionManager are broken. They should extend their own AbstractViewHelper instead of relying on Fluid's defaults and misuse the render method.

File: TYPO3_master/typo3/sysext/filelist/Classes/FileList.php

class FileList extends \TYPO3\CMS\Backend\RecordList\AbstractRecordList {
    // snip

    /**
     * Returns list URL; This is the URL of the current script with id and imagemode parameters, that's all.
     * The URL however is not relative (with the backpath), otherwise GeneralUtility::sanitizeLocalUrl() would say that
     * the URL would be invalid
     *
     * @return string URL
     */
    public function listURL() {

File TYPO3_master/typo3/sysext/backend/Classes/RecordList/AbstractRecordList.php

abstract class AbstractRecordList {
    // snip

    /**
     * Creates the URL to this script, including all relevant GPvars
     *
     * @param string $altId Alternative id value. Enter blank string for the current id ($this->id)
     * @return string URL
     */
    public function listURL($altId = '') {

So yes, it's still the case, no need to "test" to see that the subclassed method is not showing the same method signature (well, not a "compatible one")

this example has been solved with #71759, different arguments produce an exception with php7.
