An internal error occurred during: "TestNG Result Listening Job". Port value out of range: -1

Question

After installation of the update for eclipse on 1/2/2017 I got an error even for previously working tests:

An internal error occurred during: "TestNG Result Listening Job". Port value out of range: -1

I googled how to fix that - made an update for JRE to the last version 1.8.0_112 and uninstalled TestNG-Maven integration plugin but still got an error. Could somebody help me to fix the problem?

Console:

java.lang.IllegalArgumentException: port out of range:-1 at java.net.InetSocketAddress.checkPort(Unknown Source) at java.net.InetSocketAddress.(Unknown Source) at java.net.Socket.(Unknown Source) at org.testng.remote.strprotocol.BaseMessageSender.connect(BaseMessageSender.java:60) at org.testng.remote.strprotocol.MessageHub.connect(MessageHub.java:31) at org.testng.remote.AbstractRemoteTestNG.run(AbstractRemoteTestNG.java:105) at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:236) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:81)

Error log:

java.lang.IllegalArgumentException: Port value out of range: -1 at java.net.ServerSocket.(Unknown Source) at java.net.ServerSocket.(Unknown Source) at org.testng.remote.strprotocol.BaseMessageSender.initReceiver(BaseMessageSender.java:127) at org.testng.eclipse.ui.TestRunnerViewPart$3.run(TestRunnerViewPart.java:444) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

Thank you!

I restored my Windows 10 an got no error any more.. It looks like there were no problems with Java, Eclipse or my code

I'm not sure why on your local that failed to get a free port:

public static int findFreePort() {
// Nick: either here throws IOException
    try (ServerSocket socket = new ServerSocket(0)) {
// Nick: or, here return -1
        return socket.getLocalPort();
    } catch (IOException e) { 
    }
    return -1;      
}

made an update for JRE to the last version 1.8.0_122

do you mean JRE 1.8.0_112 (rather than 122)? do you have any anti-virus could impact the code?

or could you put the above code into a simple one-class java app, print the return value of findFreePort, and debug if you can reproduce in this simple app?

This sounds like a Winsock problem, not a problem with testNG itself. You can reset your Winsock installation to setup defaults by following the instructions from this KB article.

Try below steps in short:

1. in command prompt run netsh winsock reset
2. restart computer
