B4J Question How to close communication correctly?

[kabron]

Sub mnuClose_Action

    If astream.IsInitialized Then
    astream.Close
    serial.close      
    Else
    Msgbox.Show("No CommPort Selected", "ERROR")
    End If
End Sub

I get error messages on both commands:

for astream.close:

java.lang.InterruptedException: sleep interrupted
    at java.lang.Thread.sleep(Native Method)
    at anywheresoftware.b4j.serial.Serial$1.read(Serial.java:122)

    at anywheresoftware.b4a.randomaccessfile.AsyncStreams$AIN.run(AsyncStreams.java:197)
    at java.lang.Thread.run(Thread.java:745)

and for serial.close:

    at jssc.SerialPort.checkPortOpened(SerialPort.java:862)
    at jssc.SerialPort.getInputBufferBytesCount(SerialPort.java:786)

    ... 3 more

what is wrong? And how to do it correctly?
Thanks in advance

Pardon, I found solution
Erel: "If you only see the InterruptedException message in the logs then you can ignore it."
