java.lang.classnotfoundexception：org.apache.coyote.http11.http11 protocol

Question

将Apache Tomcat从9.0.48升级到9.0.62版本后，我的应用程序开始抛出以下错误： -

org.apache.catalina.startup.Catalina.stopServer Error stopping Catalina
    org.apache.catalina.LifecycleException: Failed to stop component [StandardService[Catalina]]
        at org.apache.catalina.util.LifecycleBase.handleSubClassException(LifecycleBase.java:440)

[main] org.apache.catalina.connector.Connector.<init> Protocol handler instantiation failed
    java.lang.ClassNotFoundException: org.apache.coyote.http11.Http11Protocol

我还检查了/conf/server.xml文件，它还正确地使用了连接器协议

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLSv1.2" />

不确定是什么原因导致此错误。
