"java.lang.UnsupportedClassVersionError: testJava : Unsupported major.minor version 51.0"

51.0 is jdk 7 and I have the same thing when I set eclipse or netbeans to jdk 8 ( with 52.0 instead of 51.0 )

Is there a problem with OSX or Max with it that I wouldn't know ?

Don't you only hav JDK 6 on Mac? I remember having this a while back when deploying my stuff on Mac and had to switch back to building with 6...

Well, Max on Mac doesn't support Oracle Java but only the Mac version Java For OS X. Unfortunately Java For OS X isn't part of OS X anymore since Mavericks and and the upgrade removed the old package. According to Cycling'74 it's on their list to support Oracle Java... Let's hope for Max 7. Until then there is no other way than installing the old Java for OS X (only as Java 6 available) instead of or alongside to Oracle Java:

Which also means Max Java Classes can't be developed in Java 7 or 8...

yes this is as right as known and I didn't even notice this was the "problem" here !

Anyway, Java 6 is very ok for what I'm doing and fast enough too ;)
