Description

Using the Scala API from Java, one can do:

EventFilter defaultDebug = EventFilter.debug(null, null, "", null, Integer.MAX_VALUE);
system.eventStream().publish(new TestEvent.Mute(Arrays.asList(defaultDebug)));

But with the Java testkit EventFilter there is no way to do that since creating a Scala API EventFilter is hidden inside of it.

There should be a way to do the same from Java using akka.testkit.javadsl.EventFilter

Contributor guide

Research direction
Explore the existing Java EventFilter class and implement a method to create a Mute event similar to the Scala API, following the pattern used in other Java testkit classes.
