Eclipse Java EE IDE for Web Developers. Version: Luna Release (4.4.0) Build id: 20140612-0600

A possible work-around: Eclipse Luna 4.4.0 and 4.4.1 does include support for method reference syntax, but not in the in-line context you're trying. It does work if you declare the method reference as a variable with a specific type, however. Like this:
Function methodRef = String::valueOf;
new LinkedList().stream().map(methodRef);
In this code, content-assist works correctly at the ::
