GWT 2.1编辑器框架如何支持原始类型？

package com.example;

import jsinterop.annotations.JsType;

@JsType(isNative = true)
public class IntWrapper {
    public int value;

    public IntWrapper(int value) {
        this.value = value;
    }
}

<module>
    ...
    <inherits name="com.google.gwt.core.Core" />
    <inherits name="com.google.gwt.core.CoreNative" />
    ...
</module>

package com.example;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;

public class MyApp implements EntryPoint {
    public void onModuleLoad() {
        IntWrapper intValue = new IntWrapper(42);
        // 使用intValue进行原始类型的操作
        ...
    }
}
