org.glassfish.jersey.jdkhttp.JdkHttpServerFactory is leaking sun.net.httpserver.HttpConnection if POST to a non-exist endponit

Step to reproduce:

1\. create a http server using JdkHttpServerFactory.createHttpServer
2\. curl -v --data "aaa=bbb" [http://localhost:8006/path/to/non/exist/endpoint](http://localhost:8006/path/to/non/exist/endpoint) for several times.
3\. if using apache bench to send a bunch of requests, sooner the target jvm will start to do fullgc.

In our production server, the heap dump tell us that over 300k HttpConnection(sun.net.httpserver.ServerImpl#reqConnections) objects can never be garbage collected.

Further investigation shows that in org.glassfish.jersey.server.ServerRuntime#process, a NotFoundException is thrown if the endpoint is not found, therefore in nowhere has the related HttpConnection object been released.
#### Environment
mac
#### Affected Versions
[2.24.1]

Reproduce the repeated POST requests against JdkHttpServerFactory.createHttpServer, then inspect ServerRuntime#process and the NotFoundException path alongside sun.net.httpserver.HttpConnection and ServerImpl#reqConnections. Done means nonexistent POST endpoints no longer leave HttpConnection objects retained and repeated requests no longer drive unbounded connection growth or full GCs.
