读取请求时出现org.apache.coyote.AbstractProtocol$ConnectionHandler.process错误，已忽略

Question

使用Tomcat server 8.5.4作为独立服务(tomcat8w.exe)，当我停止服务器时，我在'logs/tomcat8-stderr.YYYY-MM-DD.txt‘中得到以下错误：

org.apache.coyote.AbstractProtocol$ConnectionHandler.process Error reading request, ignored
java.lang.NullPointerException
at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.getSslSupport(NioEndpoint.java:1349)

at java.lang.Thread.run(Thread.java:745)

我的连接器如下：

<Connector SSLEnabled="true" clientAuth="false" keyAlias="xxx" keystoreFile="F:\Programs\apache-tomcat-8.5.4\certificate\xxx.keystore" keystorePass="xxx" maxThreads="150" port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" sslImplementationName="org.apache.tomcat.util.net.jsse.JSSEImplementation" scheme="https" secure="true" sslEnabledProtocols="all" sslProtocol="SSL"/>

你对这里可能出现的问题有什么解释吗？

经过研究，我发现用'org.apache.coyote.http11.Http11Nio2Protocol‘替换'org.apache.coyote.http11.Http11NioProtocol’是可行的。我解决了我的问题，但仍然欢迎对此问题的任何评论/建议或解决方案。
