This has been a problem since I started with JavaFX 8 a couple months ago, I just didn't have time to log it yet. My test app can be found at https://www.dropbox.com/sh/06yoh97jrtu36nj/7prK0vM5Sx

Running through proxy
- Going to Thingiverse WebView throws alot of error mesages and sometimes also NullPointers. It also can't display many of the images on the website. In my demo app I didn't add code to download, but in my main app I can download from websites. Downloading from Thingiverse with proxy enabled causes a timeout
- Can't go to CubeHero. I can go to CubeHero through Chrome and using the same proxy
- Can't go to YouMagine. I can go to YouMagine through Chrome and using the same proxy

Not using a proxy
- Still many errors from Thingiverse and many of the images can't display
- Can go to CubeHero
- Can go to YouMagine



Some of the errors that show up with or without proxy. I haven't been able to produce the NullPointers now
