CXF 3内存泄漏

Question

我有一个从wsdl创建的web服务，并没有改变任何东西，所以我拥有的是一个空的应用程序。

部署应用程序后，只要我点击'停止'（即我甚至没有调用它），我从Tomcat'SEVERE'消息和泄漏测试报告我的应用程序有多个实例，并增加每个我停止/开始的时间。

我使用CXF 3.1.0，甚至尝试下载最新的JAXB（参考实现从网站）。

的错误如下：

    cWorkQueueImpl.java:353)

这似乎是一个known limitation of the JAXB API。发布声明，您可以通过明确关闭Unmarshaller来避免此问题，但我自己并没有尝试过。
