Re: GWT 2.8 Compiler Question for Streams

stream() method is not mentioned in http://www.gwtproject.org/doc/latest/RefJreEmulation.html#Package_java_util. Maybe this is the reason.

Any reason why I would be receiving a compiler error in the code below?

this.mybutton.addClickHandler(c -> dosomething());

//does not compile

Arrays.asList("one", "two").stream();

I am using the beta Maven release of GWT 2.8 with jdk 1.8.0_60  and am using super dev mode.  

This is either a compiler bug or a Generator has legitimately stopped creating these types.
