Anton Krosnev updated HTTPCORE-420:
-----------------------------------
Description:
I have observed the following problem on Linux with Apache HttpComponents
4.4.1 synchronous server: After calling server.shutdown(42,
TimeUnit.MICROSECONDS), if there are Keep-alive connections opened (there is
no request processing), these sockets are not closed. Only ServerSocket is
closed:
{quote}
netstat -aon | grep 58276
TCP 127.0.0.1:50658 127.0.0.1:58276 ESTABLISHED 18012
TCP 127.0.0.1:58276 127.0.0.1:50658 ESTABLISHED 18012
{quote}
In attempt to start again HTTP server on the same port a BindingException is
thrown:
bq. Caused by: java.net.BindException: Address already in use
bq. at java.net.PlainSocketImpl.socketBind(Native Method)
bq. at java.net.PlainSocketImpl.socketBind(PlainSocketImpl.java:521)
bq. at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:414)
bq. at java.net.ServerSocket.bind(ServerSocket.java:326)
bq. at java.net.ServerSocket.<init>(ServerSocket.java:192)
bq. at
javax.net.DefaultServerSocketFactory.createServerSocket(ServerSocketFactory.java:170)
bq. at org.apache.http.impl.bootstrap.HttpServer.start(HttpServer.java:116)
On Windows the behavior is the same , however there is no BindingException and
the server starts process requests without any problems.
I will provide link to example client and server, which can reproduce the
problem.
