Quick follow up.  I was hoping to put together a simple fix for this
for 12.0, but looks likely more complicated to achieve than I hoped -
need to move/copy code from
https://github.com/apache/netbeans/blob/master/platform/core.windows/src/org/netbeans/core/windows/view/ui/MainWindow.java#L123
to 
https://github.com/apache/netbeans/blob/master/platform/core.startup/src/org/netbeans/core/startup/Splash.java
since Eirik's changes, which is easy enough, but the correct value is
not available there.  Workaroundable, but possibly intrusive change
now.

Another workaround appears to be to make sure the .desktop file
matches the name of the window - eg. apache-netbeans-ide-11.3.desktop
appears to stop the duplication.  We might want to do that with the
installer too.

Not sure why this doesn't affect the Snap - different launching logic I guess.

Best wishes,

Neil

Thanks.  Just had a bit of time to dig into this.  I can replicate
your issue with the duplicate launcher icon appearing, as of 11.2 -
earlier versions are fine.  I can't replicate the WM_CLASS of the IDE
window being wrong, but it seems the splash now has a WM_CLASS of
java.lang.Thread - is that what you ran xprop on?  Earlier versions
don't seem to have any WM_CLASS on the splash as far as I can tell.
Changing the desktop file to run NetBeans with --nosplash seems to fix
the duplicate icon issue.  Not sure what changed to cause this - I
thought the splash screen changes went into 11.1?!

Note that my StartupWMClass line above was wrong - should be (note
"IDE" was missing)

StartupWMClass=Apache NetBeans IDE 11.2

It also feels familiar. I'll see if I can replicate.

Ronald, can you share your JDK version and vendor.

Yes this is the user list. We have a separate one called dev for those 
who has the interest!

Ah, sorry, you're right - it should match the value you get from 
xprop. And does seem like the code to set WM_CLASS linked here 
doesn't work any more?!

You have not mentioned  ubuntu version , so I am hesitant to answer.

I too have created  desktop shortcut manually.

I prefer to use install kubuntu  directly after after I install ubuntu 
gnome.


because I do not want of deprive myself of free  stuff.

Anyway I have found the two important settings are

path to executable and path to icon.

I have never come across WMCLASS.

Here is  a copy of my  Netbeans  desktop short cut for kubuntu on ubuntu 18.

Hi Neil,

Ok, thanks.

I added that line to the .desktop file but I do not know what the 
correct WMClass for Apache Netbeans 11.2 is. When I enter the line you 
posted as is, I still get the duplicate icons when I launch the 
application, which means its not the correct WMClass.

What is the correct value to enter for the WMClass?
I prefer installing manually so the snap solution is not going to help me.

The answer's in your question! ;-)  Make sure to add the WM_CLASS line
to the .desktop file

eg.

StartupWMClass=Apache NetBeans 11.2

Also if you install it from https://snapcraft.io/netbeans then the 
desktop file would be correct.
