EventSemaphore (Payara Project 6.2023.2 API)

java.lang.Object
- com.sun.jts.CosTransactions.EventSemaphore

```
public class EventSemaphore
extends Object
```
The EventSemaphore interface provides operations that wait for and post an event semaphore.
This is specifically to handle the situation where the event may have been posted before the wait method is called. This behaviour is not supported by the existing wait and notify methods.
