Update: Just use the 8.40.10 final release now!
With the recent release of JDK 8u60, a lot of people are reporting that ControlsFX no longer works. This is because private APIs that ControlsFX depends on changed in 8u60, and as such we have needed to update our library to deal with this. For those of you who are using JDK 8u60 and want to make use of ControlsFX, please use the latest 8.40.10-SNAPSHOT builds that are available on Sonatype.
ControlsFX 8.40.10 will be released in the next few months. There are a lot of pull requests to merge, and this release will probably be quite a feature-packed release, if the community contributions are anything to go by! Also, Eugene and I will be presenting about ControlsFX again at JavaOne this year, so if you are attending, be sure to come along and say hi!
