关闭＆＃34; RHINO使用警告＆＃34; for HtmlUnit

Question

我使用的是HtmlUnit 2.27，目前我有以下设置

    LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log",
            "org.apache.commons.logging.impl.NoOpLog");
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript.StrictErrorReporter")
            .setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript.host.ActiveXObject")
            .setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript.host.html.HTMLDocument")
            .setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.html.HtmlScript").setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit.javascript.host.WindowProxy")
            .setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);
    java.util.logging.Logger.getLogger("org.apache").setLevel(Level.OFF);

但我仍然收到如下的Rhino警告。

RHINO USAGE WARNING: Missed Context.javaToJS() conversion:
Rhino runtime detected object

无论如何要防止打印Rhino警告？
