Unsupported major.minor version 52.0

Postby manuNDL » Tue May 09, 2017 1:56 am

Hi everybody,

I have a java program controlling my house running on Sbc for years (5years).
My Sbc crashes every two or three months (I never understood why, maybe a memory leak).
Anyway, I make a factory reset and reinstall everything at each time.
But yesterday, my PC crashed as well, damn it..
So I did the reinstall from another PC.
And no way to make my java project run.
With this error message: unsupported major.minor version 52.0
On this new PC my JDK is jdk 8, and phidget21.jar up to date.

Thanks for your help
Emmanuel

Ok...
I managed to find a solution.
Installing an old jdk 6 on my PC and compiling my project on it worked.

Does it means that the jdk on the Sbc cannot be updated more than 6?
Or did I do something wrong?
