WorkManager (Payara Project 6.2023.2 API)

java.lang.Object
- org.jvnet.hk2.config.WorkManager

All Implemented Interfaces:

Executor
```
public class WorkManager
extends Object
implements Executor
```
Simple helper for managing work sent to a foreign executor service.
Has similarities to Fork and Join.
The implementation is designed such that Tasks-1 are sent to the executor service for possibly another thread to handle. The last task is executed by the caller thread so that all threads are attempted to be fully utilized for processing including the caller's thread.
