[jira] [Comment Edited] (GUACAMOLE-414) Certain VNC servers result in disconnection due to TLS errors

-----------------------------------------------------------------

I've reproduced this in the following environment...
* Guacamole Client (git master) and guacd (git master) on Ubuntu 18.04.2, JDK 8
* CentOS7 with TigerVNC using securitytypes=TLSNone

Unfortunately I'm having trouble getting enough data other than what's already been posted as to why it's crashing.  gdb isn't overly-helpful because the process isn't crashing, per se.  Might try strace.

> Connecting to certain VNC servers such as Ubuntu Desktop (all versions I have ever run) and a CentOS based Browser Docker ([https://hub.docker.com/r/consol/centos-xfce-vnc/]) cause frequent TLS errors and consequently disconnections. The errors in the log are as follows:
> {noformat}
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error reading from TLS: The TLS connection was non-properly terminated..
> Oct 12 14:54:59 2004ff6050af guacd[8440]: read (4: Interrupted system call)
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error handling message from VNC server.
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Internal VNC client disconnected
> {noformat}
