将对象从Java传递到Jython时保留Java类型

public class JavaObjectWrapper extends Class {
    private Object object;

    public JavaObjectWrapper(Object object) {
        this.object = object;
    }

    public Object __tojava__(Class<?> cls) {
        return object;
    }
}

java_object = JavaObjectWrapper(java_object)
python_object = java_object.__tojava__(java.lang.Object)
