I have a Spring boot 2.25.1 application which is using Camel 2.25.1 with camel-kafka everything is working fine.. In my Kafka consumer, I have a need to add the feature to pause consumption on demand so I upgraded to camel 3.18.1 so I can use the pausable feature. After upgrading to 3.18.1 I am getting error FileNotFound with class file TimeoutAwareAggregationStategy.class.

when I opened camel-core 3.18.1 jar this class does not exist which was available in came 2.25.1 version.

Please suggest.

I was expecting smoother upgrade from camel 2.25.1 to camel 3.18.1.

According to the Camel upgrade guide for Camel 2.x to 3, the camel-core was modularized and broken up into multiple jar files. In that upgrade guide, they mention a lot of changes to Aggregation Strategies. While I couldn't find a direct implementation of the AggregationStrategy interface called TimeoutAwareAggregationStategy, I can see that class exists in camel-core in version 2.25.4 and the AggregationStrategy interface is moved to camel-api in version 3.0.

Normally, when upgrading a major version to a newer major version, there will be major changes that you have to account for. These changes are almost always covered in the change list or upgrade guide.
