Symptoms

JavaRDP client disconnects user's session when user interacts before the handshake is complete.

Impact

Because the RDP handshake is not completed at this point, the server aborts the connection.

Conditions

The might occur when the network connection is slow but the user is fast enough to click the mouse within the client area or press a key on the keyboard. In this case the RDP client attempts to send this input event to the server.

Workaround

Do not interact within the client area before the window fills with an image from the server. When that occurs, the connection is clearly established and all handshakes are completed.

Fix Information

JavaRDP client session starts correctly now, and the system does not process extraneous input that occurs before the handshake completes.
