I'm running community version 4.0.0.005M1 on Mac OS X 10.8.5. I have Java 1.7 Update 51 installed. When I run a graph, I get the following error in the Console:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/jetel/main/runGraph : Unsupported major.minor version 51.0
	at java.lang.ClassLoader.defineClass1(Native Method)

	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

I assume the community version I'm using doesn't like this version of Java? If so, what version should I be running?

Thanks,

Brian

  Hello Brian,
  
  CloverETL 4.0.0-M1 is not officially released yet. We had a bug in our system for a while allowing users to download it. However, the installation package was incomplete and definitely not ready to release. The error you see is probably a result of that incompleteness. Please uninstall this version and download the correct version 3.5.0 instead. If the issue persisted even there, please do not hesitate and let me know.
  
  We are sorry for the confusion.
  
  Regards,

  I did download 3.5 and that is what I'm running now. Did I need to do anything to uninstall on the Mac other than delete the app itself?

  No, you don't have to do anything else. Just delete CloverETL Designer.app directory and the uninstallation is done.
