Reports unresolved channel attributes in @StreamListener, @SendTo, @Output, and @Input annotations.

Using invalid binding name results in 'bean not found' error at runtime.

Example:

  @EnableBinding(Sink.class)
  public class LogSource {
    @StreamListener(Sink.class)
	  public void log1() {
    }

    @StreamListener("invalid")  // Reports 'Cannot find channel'
	  public void log2() {
    }
  }
