Description

I’m facing some issue when I try to quit my application. It seems connection.close() is not stopping all pending threads. Is this a known issue or am I doing something wrong?

String url = "s7://...";
PlcDriverManager manager = new PlcDriverManager();
PlcConnection connection = manager.getConnection(url);
connection.close();
System.out.println("closed”);  // gets printed but hangs afterwards

I created a thread dump which is attached.
