I'm trying a simple application with JNetwork. In Windows 7 runs correctly but in Linux the main windows appears for a fraction of second and then close.
Seems that the error occour in "Server.Initialize(23, "Server")"
Someone are able to reproduce the problem? The example is in attachment.
You have two options to see the crash logs:
1. Connect to the computer with B4J-Bridge and run the app from the IDE.
2. Run it from the command line with java -jar.
You cannot open a port lower than 1024 without root permissions.
