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.

Yes, there's a good chance that un-installing all open source Java versions is a good idea.
Then, install Oracle Java 6 or 7. It always works for me.

Why not using the version available here? It comes with a copy of a JRE 6 so you don't need to worry about the version of Java installed on your computer. Its main issue is that the items of its menu bar are not very visible with some themes of Ubuntu.

Ahhh, thanks for the replies, both of you. OK, I did see that version out there. I think I'll try that first and see if that fixes it. If it does, then I'll install Oracle 6/7 as hansmex suggests.

OK, guys. The stand-alone portable dude did it. It works perfectly using that. Thank you soooo much! I'll just run it this way. If anyone else reads this, the permissions aren't set for the java executeables so you'll have to set it yourself or it won't run.

Also, I ran it under VirtualBox with Windows XP and it said my graphics drivers weren't up to date. Maybe it meant the XP drivers though...

Regardless, I'm very pleased it's working now!!!!
