Hi, I've just installed 10.5.1 and thought to upgrade my java as well. However after doing this I have several problems. My main issue is that I cannot compile using JDK 7 and UI Designer. I get the error "Unsupported class version error" pointing to my extension of JPanel. I think this is compiled with JDK 7 but the rest of the UI Designer parts are compiled with JDK6. How can I switch this? I see only JDK 6 as a part of the IntelliJ file structure.
I also found that it is impossible to run swing with x64 JREs (I'm using Vista), however it compiles fine with x64 JDKs. Does anyone know how to get x64 JREs to run swing?
