ExtensionManagerHolder (nifi-framework-nar-utils 1.23.2 API)

```
public final class ExtensionManagerHolder
extends Object
```
Holds a singleton instance of ExtensionManager. NOTE: This class primarily exists to create a bridge from the JettyServer to the Spring context. There should be no direct calls to this class outside of the JettyServer or the ExtensionManagerFactoryBean. The rest of the framework should obtain an instance of ExtensionManager from Spring.
