java - org.apache.coyote.AbstractProtocol$ConnectionHandler.process 读取请求时出错，已忽略

Question

将 Tomcat 服务器 8.5.4 用作独立服务 (tomcat8w.exe)，当我停止服务器时，我在“logs/tomcat8-stderr.YYYY-MM-DD.txt”中收到以下错误:

org.apache.coyote.AbstractProtocol$ConnectionHandler.process Error reading request, ignored
java.lang.NullPointerException

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"/>

您对此处可能出现的问题有任何解释吗？

经过一些研究，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，但仍然欢迎对此发表任何评论/建议或解决方案。
