"Closing Group Chat Room error" when exit Spark

Spark Spark Support
1

morning everyone. i’m using Spark 2.6.3

if i leave any group chat room opened and select Spark menu Exit, client log will show:

SEVERE: Closing Group Chat Room error.

java.lang.IllegalStateException: Not connected to server.

i wonder if it is useful to change the order of following code in org.jivesoftware.MainWindow:

from:

public void shutdown() {
        final XMPPConnection con = SparkManager.getConnection();         if (con.isConnected()) {
            // Send disconnect.
            con.disconnect();
        }         // Notify all MainWindowListeners
        try {
            fireWindowShutdown();
        }
        catch (Exception ex) {
            Log.error(ex);
        }
        // Close application.
        if(!Default.getBoolean("DISABLE_EXIT"))
            System.exit(1);     }

to:

public void shutdown() {
        final XMPPConnection con = SparkManager.getConnection();         // Notify all MainWindowListeners
        try {
            fireWindowShutdown();
        }
        catch (Exception ex) {
            Log.error(ex);
        }         if (con.isConnected()) {
            // Send disconnect.
            con.disconnect();
        }         // Close application.
        if(!Default.getBoolean("DISABLE_EXIT"))
            System.exit(1);     }
