Thanks @Jens
So I added *namespace = JsPackage.GLOBAL* as suggested:
package com.project.client;
import jsinterop.annotations.JsPackage;
import jsinterop.annotations.JsProperty;
import jsinterop.annotations.JsType;
@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public class Car {
@JsProperty(namespace = JsPackage.GLOBAL) public static Car car;
public native String start();
}
But the new stacktrace is:
SEVERE:
java.lang.ClassCastException
at Unknown.xk_g$(Throwable.java:69)

Other ideas?
