ENGINE-08043 Exception while performing 'Deployment of Process Application processApplication'

[tom.cr...@gmail.com]

Hi,

I've recently run into a problem deploying a new Spring process application on a Container (Tomcat) with a shared process engine (configured as JNDI Global resources).

I'm basically following the instructions here:

* https://docs.camunda.org/get-started/spring/shared-process-engine/
* https://docs.camunda.org/manual/7.4/user-guide/spring-framework-integration/configuration/#configure-a-container-managed-process-engine-as-a-spring-bean

When deploying the second process application, the following exception occurs (stacktrace below).

Am I doing something wrong?

Using camunda 7.4.0

It seems the problem occurs when the SpringServletProcessApplication bean has the same name ("processApplication") in two process applications' applicationContext.xml. I've changed the name in one of the applications and both now deploy successfully.
