JDK 7 and IntelliJ 10.5.1 don't play nice together

Hello Mikael,

To work with components built with JDK 7 in the UI Designer, you need to
run IntelliJ IDEA itself under JDK 7. (The JDK that it has been compiled
with, as well as the 32/64 bit difference, does not matter.)

In order to do that, you need to define the IDEA_JDK environment variable
and point it to your JDK 7 installation.

Hi, I've just installed 10.5.1 and thought to upgrade my java as well.
However after doing this nothing works. I found that it is impossible
to run swing with x64 JREs, however it compiles fine with x64 JDKs. My
main issue however 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 IntelliJ.

Does anyone know how to get x64 JREs running swing?
