Simple types int/bool/double cause Exceptions when beeing mapped
There is an issue when using aliased simple (target) types (int/bool/double) in PHDoc. During mapping it correctly identifies them as integer/boolean/float but fails to map them, because there is no type handling definition for int etc.
This can be remedied by calling \TYPO3\CMS\Extbase\Utility\TypeHandlingUtility::normalizeType() in the PropertyMapper (see attached patch).
Found in 6.2.9, still relevant in 6.2.11.
