Description

ActorAdapter will ignore null message with "Adapter function returned null which is not valid as an .."

However, this seems not be documented. For instance, scaladoc/javadoc of pipeToSelf could mention it as well as any other place where adapters are used.

Contributor guide

Research direction
Locate the ActorAdapter class and the pipeToSelf method in the source code. Examine how null is handled and identify where in the scaladoc/javadoc the behavior should be documented.
