Guava EventBus dispatching

Question

I\'m using Guava\'s EventBus to kick off some processing and report results. Here\'s a very simple compilable example:

import com.google.common.eventbus.EventBu

I know this question is 4 years old, but I just ran into the same problem today. There is a simple (and counter-intuitive) change to get the behavior you want. Per https://stackoverflow.com/a/53136251/1296767, you can use an AsyncEventBus with a DirectExecutor:

public static EventBus bus = new AsyncEventBus(MoreExecutors.newDirectExecutorService());

Running your test code with the above change, the results are exactly what you want:

Got processing request - starting processing
Processing has started
Generating results
got results
Generating more results
got results
Processing has completed
