bbb 1.1 - deskshare on icedtea (linux)

[Michael]

Hi there!

New deskshare in bbb works perfectly fine (tested on Windows). But I found one problem, while using it on my desktop ubuntu 14.04

darkfess@DFZ:~$ java -version
java version "1.7.0_121"
OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.14.04.3)
OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

It looks something like this:

So application starts, but deskshare not working.

Looks like it uses http://icedtea.classpath.org/wiki/IcedTea-Web#Netx (javaws) so:

darkfess@DFZ:~$ javaws -about
icedtea-web 1.5.3 (1.5.3-0ubuntu0.14.04.1)

*  The IcedTea-Web project provides a Free Software web browser plugin running applets written in the Java programming language and an implementation of Java Web Start, originally based on the NetX project. Visit the IcedTea-Web homepage: http://icedtea.classpath.org/wiki/IcedTea-Web . Use "man javaws" or "javaws -help" for more information.
*  Names and email addresses of contributors to this project can be found in the file AUTHORS in the IcedTea-Web root directory.
*  News about releases of this project can be found in the file NEWS in the IcedTea-Web root directory.
*  The full GPLv2 license of this project can be found in the file COPYING in the IcedTea-Web root directory.
Launching about window...

Here it is: https://launchpad.net/ubuntu/+source/icedtea-web

Will it work? Or may be I need some configuration on my desktop.. etc? Thx for advice.

Hi,

Can you please tell us what Linux distribution and version you are
using?

Sorry, I missed your earlier message that said you were using Ubuntu
14.04. We haven't actually tested the applet on anything older than
Ubuntu 16.04 - is it an option for you to try the newer Ubuntu version?

We'll take a look at testing more in Ubuntu 14.04, but it's so out of
date now as a desktop OS that we're not sure we'll be able to fully
support it.

Hi Calvin, okay thx.

So, resolution: purging OpenJDK 7 and installing Oracle JDK 8 resolves the problem.

Hello,

I have tried sharing my screen using Firefox 54.0 (64 bits) on Elementary OS Loki (Ubuntu 16.04.2) with OpenJDK 1.8.0, and I see a similar behaviour as Michael:
