# Breaking: #63838 - Changed OpcodeCacheUtility being a service class

See [forge#63838](https://forge.typo3.org/issues/63838)

## Description

The `OpcodeCacheUtility` has been migrated to a service class called `OpcodeCacheService`, all methods are not static anymore.

## Impact

Calling `OpcodeCacheUtility` will throw a fatal error.

## Affected Installations

All third-party extensions using the utility class will be affected.

## Migration

Create an instance of `OpcodeCacheService` and call its method by the object operator `->`.

Example:

```php
GeneralUtility::makeInstance(OpcodeCacheService::class)->clearAllActive($cacheEntryPathAndFilename);
```
