Re: Compiler error with the latest gwt head ?

The issue seems to be with usage of the new Elemental2 libraries. It looks like it has not much to do with my Java code, just the inclusion of Elemental2 breals the compile.

   <inherits name="elemental2.core.Core"/>
   <inherits name="elemental2.dom.Dom"/>

Switching to the old JSNI Console logging works:

@EntryPoint
public class Main {

    @Inject
    private Caller<Ping> ping;

    @Inject 
    private Console console;

    @AfterInitialization
    private void afterInitialization() {
        ping.call((String response) -> {
            console.log(response);
        }).ping();
    }
    
    // If I switch to this, it works
    public static native void log(String message) /*-{
        console.log(message);
    }-*/;
}
