What is the situation with JavaFX on Linux (x86 and x64)?
Can a JavaFX app be executed without problems on Linux OS?
I have found some questions from years 2011 and 2012, when apps were not stable!
The current version of JFX released is 2.2.4 and it is quite stable on Linux. However, it will become very much better when Java 8 would be released as it would contain JFX 8 distibution. You can try it yourself now using java 8 early access builds.
JavaFX 8 runs fine on Linux in my experience, the only requirement appears to be libgtk 2.18+. There are full details on Oracle JDK 8 and JRE 8 Certified System Configurations. Working Linux versions include:
