I'm trying to use IDEA 8.1 on Windows 7. I have JDK 1.6.0_12 at C:\Program Files\Java\jdk1.6.0_12. I'm running this on Parallels which I suspect *may* be the problem, but I really have no idea.
When I use a Java type (such as String) the type is highlighted in red and the error highlighting says "Cannot resolve symbol String". But I can compile and run just fine from within IDEA.
When I go to the settings and change the JDK, for example to "no jdk" then back to "1.6", the indexing dialog pops up briefly and appears to be reading from C:\Program Files\Java\jdk1.6.0_12\...... But the error highlighting persists.
I wondered if anyone has gotten 8.1 working on Windows 7 Beta? If no one has had this issue I guess my conclusion is that I can't use it on Parallels. My next step is to try IDEA 7 if I can find a download for it.
