Locking up on splash screen
I am a C/C++ 3D Game developer, just for background info. I need to design an addition to my daughter's house and I run Ubuntu 14.04. I had Sweet Home installed from the Ubuntu package and it was working just fine, but I wanted the latest software and downloaded 5.0. Well, it doesn't work. I think because of this:

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedClassVersionError: sh3d_plugin/AdvancedSettings_PhotoRendering : Unsupported major.minor version 52.0

So, maybe you'd suggest running from the jar, like this:

java -Dcom.eteks.sweethome3d.no3D=true -jar ./SweetHome3D-5.0.jar

But, I get the same error...

Admittedly, I'm not a JAVA person, and almost cringe when I hear the word, but I can read the stuff. That's about it though. What does Unsupported major.minor version 52.0 mean??

Don't tell me that my video drivers are obsolete or anything like that because they're not. I develop 3D software constantly on this machine.

My JAVA scoop:
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

Do I need 1.6?? Do I need the Sun version?

Thanks for any help guys!! If I can't fix it I'll just trash it and move on.
