I am a little confused about what to do to make generics
Your instructions say to put gjc-rt.jar and collect.jar to lib/generics, however the start scripts uses lib/generics/2.0/ (in idea.bat) on the boot class path.
I have put the jars in both directories :)
When I check the generics box in the compiler settings generic code compiles fine.
However I have not managed to get rid of the errors displayed in the editor whenever I use generic collections, such as List]]>.
I have tried to put add generic sources also and moved them in front of the JDK on the Order tab, but still no luck.
