Nio2Endpoint.Nio2SocketWrapper.getSslSupport Exception in springboot application

Question

I implemented a self-signed ssl certificate for a the spring boot application. Although the results are coming as expected, I getting the below exception is thrown. Using Springboot: 2.1.8 and Tomcat: 9.0.24

I tried changing the protocol from 'org.apache.coyote.http11.Http11NioProtocol' with 'org.apache.coyote.http11.Http11Nio2Protocol'. But still getting the exception.

The exception thats thrown.

@Bean
    public TomcatServletWebServerFactory tomcatServletWebServerFactory() {
        TomcatServletWebServerFactory tomcatServletWebServerFactory = new TomcatServletWebServerFactory();
        tomcatServletWebServerFactory.setProtocol("org.apache.coyote.http11.Http11Nio2Protocol");
        return tomcatServletWebServerFactory;
    }

That is a known bug in Tomcat 9.0.24. It is triggered when you try and use plain text on an TLS enabled connector. The bug is fixed in the recently released 9.0.26.

Yes. I found the same in the in Bugzilla. But currently after upgrading to tomcat 9.0.26 , and when I try to execute the Jar that is created I am getting 'The port may already be in use or the connector' exception. This is only happening while executing the jar and not through bootRun. – Joel George Sep 23 '19 at 10:38
This is happening only with 9.0.26 tomcat. The same code is working fine with 9.0.24. Not sure why? – Joel George Sep 23 '19 at 10:41
