idea中测试hprose tomcat 关闭时 hprose报错误信息

[ammonzhang]

hprose-php 做服务端，hprose-java做客户端 结合 springmvc
idea里能正常启动tomcat,没有错误信息，并且可以访问到hprose-php服务端的数据。
但关闭tomcat时，提示如下：
严重 [main] org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [ROOT] created a ThreadLocal with key of type [hprose.io.ByteBufferStream$1] (value [hprose.io.ByteBufferStream$1@5f3a4b84]) and a value of type [hprose.io.ByteBufferStream.ByteBufferPool] (value [hprose.io.ByteBufferStream$ByteBufferPool@670b40af]) but failed to remove it when the web application was stopped.

Exception in thread "Thread-11"
是什么原因呢？

可能是线程没执行完吧，被强制退出来吧。这种问题忽略就行，反正 tomcat 都关了。
