I have read that Eclipse Neon has now support for hidpi but icons are extremely small when using a hidpi notebook in Ubuntu 16.04.
Is there any command line argument or environment variable that I have to set so it works?

At least in my case (ASUS UX303UB, Eclipse Neon 4.6.0RC1, Ubuntu 16.04), it was possible to get proper icons by adding:
at the end of
worked for me. It apparently used my Gnome Tweak Tool font scaling setting of 1.35 The autoScale options are explained at Tweaking SWT's auto-scaling
For me the following worked:
GDK_DPI_SCALE=0.5 GDK_SCALE=2 eclipse
Setting GDK_SCALE to 2 alone fixed the icon size but made all text huge. I had to set GDK_DPI_SCALE to 0.5 counter the effect on the font size.
If you want to create a launcher, use the following in the command editor (adapted from Zoltan):
env GDK_DPI_SCALE=0.4 env GDK_SCALE=2 eclipse
I'm using it on a 4k 15.6' display.
