ASA WebVPN Java RDP - connection closes when application starts


We use the java RDP Plugin on our ASA to access some Windows servers remotely. Every time a user starts a specific application on a specific server the RDP connection displays an error message "Coordinate out of bounds" and closes. One of our customers reproted this to a collegue recently too, but I have no information wich application causes this at the customer.

This is the error message we get displayed:

That´s from the java console:

60796 [Thread-14] WARN net.propero.rdp processData - java.lang.ArrayIndexOutOfBoundsException Coordinate out of bounds!

Does anyone have this problem, too?

ASA WebVPN Java RDP - connection closes when application starts

I found out, that this happens every time a application starts which has a window size greater than the resolution of the RDP session.

If I start the connection without the ASA by command line, it's the same.

java.exe -classpath properJavaRDP-1.1.jar;properJavaRDP14-1.1.jar;log4j-java1.1.jar;java-getopt-1.0.12.jar net.propero.rdp.Rdesktop xx.xx.xx.xx

Seems to be a bug in the properJavaRDP

As a work around, you can try to increase the window you are asking for:


for example, using the geometry=widthxheight parameter.
