I installed the u40 release today, and I use NetBeans 7.3 as my development environment. After I tried to build a couple of projects against the new release, and finding I couldn't run them from within NetBeans (java.lang.UnsatisfiedLinkError: com.sun.glass.ui.win.WinApplication._invokeLater(Ljava/lang/Runnable;), I went back to u25 and I was able to build and run from within NetBeans. But then I went to try to run some previously built applications (built against u25) and they won't run at all. I'm thinking it might have something to do with the packaging, but I don't know, and I'm not even sure how to find out what the problem is.
This is critical, because in my company some users may update their version of java, and if they do, my applications will cease to work.
My projects are maven projects, and I use the zenjava javafx-maven-plugin to package the apps.
TIA,
