Service task not able to find JavaDelegate class bean when "asyncExecutorActivate" is true

Thank you for the reply. As you have said, it has nothing to do with the async executor. After some research, I found out that the mistake I made was using StandaloneInMemProcessEngineConfiguration in the spring boot application. That’s why flowable was not able to find the bean.
When I used SpringProcessEngineConfiguration to build the process engine, the service task is working fine.

Then another problem raised with Business Rule Task. I have opened another topic. Please see if you have any inputs on that.

Thanks.
