Describe the bug

I am using Kogito BPMN and DMN on a Wildfly application server (CDI environment).
I have 1 main process definition and about 7 subprocesses definitions.
In order to instantiate the main process, I inject the ProjectRuntime and the Application in a singleton bean which is initialized at @startup.
I have a @stateless session bean with a method where I want to start the main process instance. The singleton bean is injected is this session bean.
In the method where I want to start the process instance I use:
`
Application application = startBean.getApplication();

Processes processes = application.get(Processes.class);
Process<? extends Model> process = processes.processById(MAIN_PROCESS_ID);
I got the error: "java.lang.IllegalStateException: Recursive update java.util.concurrent.ConcurrentHashMap.computeIfAbsent". I found a workaround, in that I instantiate all subprocesses:
processes.processIds().stream()
.filter(id -> !id.equals(MAIN_PROCESS_ID))
.forEach(processes::processById);
`
and then getting the main process, after all others are already in the map in the Processes object.
It would be nice to have this issue fixed.

An example on how to use messages with JMS would be nice.

Now I have subprocesses that in turn have child subprocesses, and the fix I used previously is not working anymore, so I had to give numbers to process ids, like "main_process_1", "subprocess_11", "subprocess_112", and so on, then sort the process ids by their number in descending order, and initialise them, which is not so nice.

@pefernan @cristianonicolai @fjtirado any idea there ?

Hi @danstancu a small reproducer would be really helpful

Hello @radtriste @pefernan @cristianonicolai @fjtirado , here is a small reproducer. I tested it on a Wildfly 16 server.
