-------------------------------------------
Hi Guys, Just found this issue and would like to respond to the question on JDK
10 Directly.
I run on Fedora 28 with Gnome 28 and OpenJDK10 with 4k monitor.
And even as of today I run into catch 22 situation with Java/Netbeans.
*Scenario 1:* Install Netbeans and start on JDK 10 no custom flags or
anything. The result, I get all components to be extremely tiny, icons,
scrollers, tabs, etc.. The fonts seem to be doing much better and push the ui
components around, I guess since GDK/Gnome adjusts them somewhat.

Scenario 2: Start Netbeans in a console with the following ENV Variables
exported.
{code:java}
export GDK_DPI_SCALE=0.5 <-- this one does not seem to help or work.
export GDK_SCALE=2
{code}
Now, Netbeans components, icons, and scrollers seem to scale correctly...
However the FONTS are 4 times larger and no matter what I do, I cannot get them
to sale to their proportional size. (See attachment)

A basic test running Netbeans with Java9 or 10 in Gnome 26 or 28 with HIDPI 4k
monitor and you cannot miss the above scenario.
I have yet to see a solution to this. I was deeply disappointed to see this and
continue to witness all along while everyone said JDK 9+ would fix scaling
issues for Java and hence for Netbeans and yet here we are!
Thank you
