It seems that Eclipse can't suggest a lambda expression or lambda code block where a functional interfaces could be used. For example, in the code snippet below, Eclipse couldn't suggest any code completion for the clip.addLineListener(). A competing Java IDE had no problem suggesting a lambda while my cursor was between the parenthesis.

==========
			Clip clip = AudioSystem.getClip();
			// Open audio clip and load samples from the audio input stream.
			clip.open(audioIn);
			clip.start();
			// Listen for STOP event so we can close the clip, otherwise we will run out of resources
			clip.addLineListener(event -> {
				if (event.getType().equals(LineEvent.Type.STOP)) {
					clip.close();
				}
			});
==========
