samples/02_InventoryStream throws java.net.SocketException: Socket closed

[baba012]

Hello,
I'm testing with a Sampo S1 (usb + ethernet) connected with the ethernet cable directly to my mac.
If I run ./run_sample.sh samples/02_InventoryStream/, when the connection with the reader is closed I see the following exception
java.net.SocketException: Socket closed at java.base/sun.nio.ch.NioSocketImpl.ensureOpenAndConnected(NioSocketImpl.java:165) at java.base/sun.nio.ch.NioSocketImpl.beginWrite(NioSocketImpl.java:366) at java.base/sun.nio.ch.NioSocketImpl.implWrite(NioSocketImpl.java:411) at java.base/sun.nio.ch.NioSocketImpl.write(NioSocketImpl.java:440) at java.base/sun.nio.ch.NioSocketImpl$2.write(NioSocketImpl.java:826) at java.base/java.net.Socket$SocketOutputStream.write(Socket.java:1035) at com.nordicid.nurapi.NurApiSocketTransport.writeData(NurApiSocketTransport.java:206) at com.nordicid.nurapi.NurPacket.write(NurPacket.java:161) at com.nordicid.nurapi.NurApi.writeThread(NurApi.java:3099) at com.nordicid.nurapi.NurApi.access$1100(NurApi.java:29) at com.nordicid.nurapi.NurApi$9.run(NurApi.java:3060) at java.base/java.lang.Thread.run(Thread.java:833)
followed by this line
Log[2]: 1680650742807 exchangeCommand() 14; write failure

Trying to debug I can avoid the exception working on the writeData() method of the NurApiSocketTransport, but I still see the line "Log[2] ....".
What is the reason of this line?
