After installing build #7656 today I got some problems. I'm not sure it acctually is connected to the upgrade but still the problem is very annoying. Suddenly I wasn't able to compile anymore with an error text with something about javac not a valid Win32 Application.
By now I pretty much tried everything from setting up a new project to completely remove and reinstall the IDEA. Now when I try to add the JDK on the freshly installed IDE I get this error:
"Probably JDK installed in 'C:/bea/jdk142_08' is corrupt"
This is all very strange because there are nothing wrong with the javac.exe file or the JDK installation since it works just fine under eclipse and Ant. What could be wrong? What does IDEA use to determine and launch the javac? I'm running out of ideas here.
