<Process> in <Threads> Migrating to Camel 3+ from 2

Question

I am migrating from camel 2.25.2 to 3.4.0. I noticed that previously in my camel-context.xml, I could put <process> in <threads></threads>. However, with the upgrade, Intellij has been complaining - "Element process is not allowed here".

For example:

<threads>
    <process ref="abcProcessor" />
</threads>

However, I could do it outside of . Upon closer inspection, I noticed the following in camel-spring.xsd:

<xs:element name="threads" type="tns:threadsDefinition">

The ThreadsDefinition class in org/apache/camel/camel-core-engine/3.4.0/camel-core-engine-3.4.0.jar!/org/apache/camel/model/ThreadsDefinition.class is different.

I tried finding for some documentation and material but to no avail on how to migrate away to 3.4.0 from 2.25.2 for process tags in threads.

This is the closest I could find: https://camel.apache.org/manual/latest/async.html

Is there a way to migrate a custom processor for message exchange that is asynchronous written in DSL?

Would appreciate if the community could give me some insights. Cheers!

Put <process> after <threads />
