Javadoc in 9 seems to treat all interfaces with only one method as functional interfaces (original) (raw)

Hi guys,

While playing with JDK 9 javadoc command I noticed that it seems to treat all single method interfaces as if they were functional interfaces - even though they don't have the @FunctionalInterface annotation. For instance - I did 'make docs' - and I'm seeing this text in the javadoc for 'java.awt.event.ActionListener': >> Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference. << Is that a known issue, or a new regression, or did I miss something? Is this JDK-8029143? From what I can tell, it hasn't been forward ported to jdk9/dev yet.
