SingletonEnforcer (Payara Project 5.182 API)

```
public final class SingletonEnforcer
extends Object
```
Enforce singleton semantics: if an item already exists, an Error is thrown. Otherwise it is recorded for future checks. This facility exists because of ugly framework requirements for singletons to offer public constructors, which can allow more than one instance of a class to be instantiated.
