ControlsFX - Exception in thread "ControlsFX Error: ControlsFX 8.40.10 requires at least Java Version 8 Update 40

I've looked at other issues similar. What I can tell you is: This program worked a week ago. I haven't changed scenebuilder. A new JRE, as I recall, was downloaded and it is 1.8.0_101-b13. This is on Linux 64bit. In the very same program Lambda notifications still work. I did just upgrade scenebuilder to 8.2.0 from 8.0.0. But I am not actively working on a fxml file.

I believe the only change was a recent upgrade on the JDK/JRE. The default computer is the same release as the default runtime.

This issue was resolved on 13 April 2016 for ControlsFX 8.40.x, but ControlsFX 8.20.x still has this problem (8.20.9 was released on 2 June 2015).

To fix the problem:

  • use ControlsFX 8.40.x or higher, or
  • use a Java version that has a two-digit minor version number (both 8u20 and 8u40 will be fine).

What is the bug? Well, ControlsFX is comparing the minor versions of Java and ControlsFX as String values: "40" is considered higher than "101" because the first character "4" is higher than "1" (source). The implemented fix parses the version strings as Integer values.

I could have sworn another issue on this was resolved by changing the version of scenebuilder...which did not, on the surface, make sense. Although there was a new SceneBuilder out there from Gluon.

This problem is fixed by upgrading ControlsFX to version 8.40.11, up from 8.40.10.
