Subject: Virtual Thread with Http11Nio2Protocol
Hi,

I try to use virtual thread on Apache Tomcat 10.1.16 with this configuration on 
macOS or on Linux:

    <Executor name="tomcatThreadPoolVirtual" 
class="org.apache.catalina.core.StandardVirtualThreadExecutor"/>

    <Connector port="8080" 
protocol="org.apache.coyote.http11.Http11Nio2Protocol"
               connectionTimeout="20000"
               redirectPort="8443"
               maxParameterCount="1000"
               useVirtualThreads="true"
               />
But when I make a request, I'm not on a virtual thread : 
Thread[#76,Thread-14,5,main] . I profiled my application too but no virtual 
threads are used.

If I use a Http11NioProtocol instead of Http11Nio2Protocol, all requests are on 
virtual thread : 
VirtualThread[#65,http-nio-8080-virt-0]/runnable@ForkJoinPool-1-worker-1

    <Executor name="tomcatThreadPoolVirtual" 
class="org.apache.catalina.core.StandardVirtualThreadExecutor"/>


    <Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
               connectionTimeout="20000"
               redirectPort="8443"
               maxParameterCount="1000"
               useVirtualThreads="true"
               />
Http11Nio2Protocol is not working with virtual threads? Has anyone encountered 
this problem before?
