Starting with Java EE 7 (now Jakarta EE), the standard provides a straight forward way of using container managed threading in applications

Before Java EE 6, it was still necessary to leverage a JCA Resource Adapter to gain access to a Container managed workmanager. Camunda Engine provides such and integration, but there are now more straight forward means to achieve this.

Scope of this FR:

• Break down use of Threading by the process engine
• Provide out of the box integration with container managed threading through the new MangedExecutorSerivice APIs [1]
• Expose configuration options
