…arDownTrait (skalpa)This PR was merged into the 4.2 branch.Discussion----------[FrameworkBundle] Removed eval() from KernelShutdownOnTearDownTrait| Q             | A| ------------- | ---| Branch?       | 4.2| Bug fix?      | yes| New feature?  | no| BC breaks?    | no| Deprecations? | no| Tests pass?   | yes| License       | MITApart from triggering the#30362 bug, the `eval()` block from#30124 also broke my workflow: static code analyzers don't like this, and the trait even crashes PHPStan.It may also bring up other compatibility issues to other people (ie: I know companies that completely disable `eval()` on their servers).As it was only required to keep the trait compatible with PHP 5.x, it is unnecessary on 4.x that requires PHP 7.1+, and this PR removes it on the 4.2 branch.Commits-------324b70a Removed eval() from KernelShutdownOnTearDownTrait
