IntelliJ IDEA 12 / MPS 2.5.3 Plugins / OpenJDK 1.7.0.1 / Fedora16
I did step by step from JetBrains TV session: "How to enable MPS in IntelliJ IDEA" - http://tv.jetbrains.net/videocontent/how-to-enable-mps-in-intellij-idea
IntelliJ IDEA dialog "Choose Main Class" isn't working. It's impossible to select the Demo class from the MPS Project Demo.
When starting IntelliJ IDEA 12, first message is:
[Techniker@L3F591407 Downloads]$ idea-IC-123.169/bin/idea.sh
OpenJDK Runtime Environment (fedora-2.3.5.fc16-i386)
OpenJDK Server VM (build 23.2-b09, mixed mode)
WARNING: You are launching the IDE using OpenJDK Java runtime.
ITS KNOWN TO HAVE PERFORMANCE AND GRAPHICS ISSUES!
SWITCH TO THE ORACLE(SUN) JDK BEFORE REPORTING PROBLEMS!
NOTE: If you have both Oracle (Sun) JDK and OpenJDK installed
please validate either IDEA_JDK, JDK_HOME, or JAVA_HOME environment variable points to valid Oracle (Sun) JDK installation.
See http://ow.ly/6TuKQ for more info on switching default JDK.
Press Enter to continue.

Since this flag is a new option of IDEA 12, we should perhaps update http://confluence.jetbrains.com/display/MPSD25/Using+MPS+inside+IntelliJ+IDEA with an explicit warning.
Would this have helped in your case?
