B4J Question Java error when closing Astream (jSerial library)

[yo3ggx]

I have a java console application which use jSerial library.
When I want to close Astream, before closing the serial port, I get the error:


java.lang.NegativeArraySizeException

at jssc.SerialPort.readBytes(SerialPort.java:421)

This error does not affect in any way the functionality of the app, but is logged to the console too.
I have tried:

Try
  If Astream.IsInitialized Then Astream.Close
Catch
  //do somthing
End Try
Serial1.Close

but the error is still logged in the console where the application runs.

What can I do to prevent this?

You can ignore it. Have you tried to close Serial before closing AsyncStreams?

 

[yo3ggx]

No, serial port is closed after Astream.
In the GUI version of the app I ignore it, as is not visible in the interface, but in the no-GUI mode, the message is displayed in the console.
There is any way to hide it?
As stated in my previous message, a Catch block does not prevent it to be displayed.

No (not without updating AsyncStreams library). The catch block is not relevant as the error happens internally.
