phpunit: PHPUnit\Util\Annotation\DocBlock instantiation problem

Q	A
PHPUnit version	8.5.2
PHP version	7.2.28
Installation Method	Composer

Current behavior

\PHPUnit\Util\Annotation\DocBlock::ofMethod tries to instantiate the DocBlock class, the problem is that it doesn’t check if the \ReflectionMethod $method that it receives contains all the needed data that is passed to the constructor. For example I ran into a case where $method->getStartLine(), $method->getEndLine() etc returns false, but the constructor expects int and everything breaks then.

Argument 4 passed to PHPUnit\Util\Annotation\DocBlock::__construct() must be of the type integer, boolean given, called in /webroot_data/webroot/vendor/phpunit/phpunit/src/Util/Annotation/DocBlock.php on line 118

How to reproduce

Call \PHPUnit\Util\Annotation\DocBlock::ofMethod with an \ReflectionMethod instance which only has the class and name properties set.

Expected behavior

The \PHPUnit\Util\Annotation\DocBlock class should be instantiated without errors.
