Web应用程序似乎已启动名为[HikariPool-1管家]的线程，但未能停止它

我正在尝试在Tomcat 8.5中使用HikariCP JNDI DataSource Factory，但是当它关​​闭时，我得到以下警告：

o.a.c.loader.WebappClassLoaderBase       : The web application [ROOT] appears to have started a thread named [HikariPool-1 housekeeper] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

我的Hiraki配置是在JNDI DataSource Factory（Tomcat等）文档之后设置的，它是这样的：

我找到了此链接， 但它无济于事，因为我将Hiraki用作Tomcat中的资源。

我正在使用Tomcat 8.5 HikariCP 2.5.1

有什么帮助吗？谢谢。
