JavaFX program start takes 12 Seconds when online

Question

I made a simple "Hello World" app from the E(fx)clipse Tutorial 1.

When starting the jar from the dist folder, my system took more than 12 Seconds. I verified that with the oracle sample apps, which behave identical.

Start up time is less than a second when I disable Wifi, thus no internet connection available. Running a Windows 7 (64 Bit) machine with Java x86, Version 7.

Is this a personal problem or can I expect this behavior on all machines where the app is deployed? Then JavaFX would be useless. Swing jars start instantly.

Answer 1

The problem is most likely the proxy resolution which was fixed with https://bugs.eclipse.org/bugs/show_bug.cgi?id=408397. If you are not on the nighlty tooling (http://downloads.efxclipse.bestsolution.at/downloads/nightly/sdk) you'd have to modify the build.xml by hand adding "<attribute name="JavaFX-Feature-Proxy" value="None"/>" to the <manifest> tag
