The PipeSocket was convenient and avoided real I/O, but the shutdown/close while connecting/handshaking tests were triggering a Socket bug in Java (https://bugs.openjdk.org/browse/JDK-8278326). Using a real socket doesn't trigger the bug because the test stops sharing state with the code under test. Fixes grpc#10228 ``` Details ================== WARNING: ThreadSanitizer: data race (pid=4528) Write of size 1 at 0x0000cfb9d5f4 by thread T36 (mutexes: write M0): #0 java.net.Socket.setCreated()V Socket.java:687 #1 java.net.AbstractPlainSocketImpl.create(Z)V AbstractPlainSocketImpl.java:149 #2 java.net.Socket.createImpl(Z)V Socket.java:477 #3 java.net.Socket.getImpl()Ljava/net/SocketImpl; Socket.java:540 #4 java.net.Socket.setTcpNoDelay(Z)V Socket.java:998 #5 io.grpc.okhttp.OkHttpServerTransport.startIo(Lio/grpc/internal/SerializingExecutor;)V OkHttpServerTransport.java:164 #6 io.grpc.okhttp.OkHttpServerTransport.lambda$start$0(Lio/grpc/internal/SerializingExecutor;)V OkHttpServerTransport.java:159 #7 io.grpc.okhttp.OkHttpServerTransport$$Lambda$56.run()V ?? #8 io.grpc.internal.SerializingExecutor.run()V SerializingExecutor.java:133 #9 java.util.concurrent.ThreadPoolExecutor.runWorker(Ljava/util/concurrent/ThreadPoolExecutor$Worker;)V ThreadPoolExecutor.java:1130 #10 java.util.concurrent.ThreadPoolExecutor$Worker.run()V ThreadPoolExecutor.java:630 #11 java.lang.Thread.run()V Thread.java:830 #12 (Generated Stub) <null> Previous read of size 1 at 0x0000cfb9d5f4 by thread T35 (mutexes: write M1, write M2): #0 java.net.Socket.close()V Socket.java:1512 #1 io.grpc.okhttp.OkHttpServerTransportTest$PipeSocket.close()V OkHttpServerTransportTest.java:1384 #2 io.grpc.okhttp.OkHttpServerTransportTest.clientCloseDuringHandshake()V OkHttpServerTransportTest.java:290 ```
