java.io.EOFException at org.apache.tomcat.util.net.NioEndpoint (tomcat 9 & openjdk 8)

Question

I am upgrading the tomcat and openjdk version for a project. Target: Tomcat 9.0.63 and openjdk-8u322-b06.

However, getting EOFException when using Tomcat 9.0.63 and openjdk-8u322-b06.

I don't know how to fix it.

Findings:

Error occurs if using Tomcat 9.0.63 and openjdk-8u252-b09 or later version.

No errors occurs if using Tomcat 9.0.35 and openjdk-8u322-b06.

No errors occurs if using Tomcat 9.0.63 and openjdk-8u242-b08 or previous version.

Solved. Tomcat 9.0.36+ and openjdk 8_252+ not support http2 and NioProtocol at the same time. It must be use apr protocol="org.apache.coyote.http11.Http11AprProtocol" and change the server.xml

<Connector port="9443" protocol="org.apache.coyote.http11.Http11AprProtocol"
           SSLEnabled="true" scheme="https" secure="true"
           maxThreads="150"
           compression="on" compressionMinSize="2048"
           noCompressionUserAgents="gozilla, traviata"
           compressableMimeType="text/html,text/xml">
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
    <SSLHostConfig protocols="TLSv1.2,+TLSv1.1" certificateVerification="none">
        <Certificate certificateKeystoreFile="xxx.keystore"
                     certificateKeystorePassword="xxx"
                     type="RSA" />
    </SSLHostConfig>
</Connector>

If using protocol="org.apache.coyote.http11.Http11NioProtocol", it needs to remove <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />, no error occurs but http1.1 only.

In addition, tomcat-native must be use. After yum install apr-devel openssl-devel, please download the lastest tomcat-native from apache. If the tomcat-native is not lastest version. It causes Failed to initialize the SSLEngine. org.apache.tomcat.jni.Error: 70023: This function has not been implemented on this platform at org.apache.tomcat.jni.SSL.initialize. — MLM, Jun 30 '22 at 04:44
