I have three UI applications that are now suddenly no longer working within IntelliJ. I am getting the following stack trace:
Exception in thread "main" java.awt.IllegalComponentStateException: contentPane cannot be set to null.
I recently upgraded from 6.x on Windows to 8.1 on the Mac. To create the most basic test, I created a new Dialog GUI with a main and all the default elements on it. I compiled and then ran it and it also gives me the above stack trace.
I have the UI generation setting to Binary class files, Automatically copy form runtime classes..., etc.
This issue that this was just working and suddenly it isnt and I pretty certain I didnt change anything.
Any insight or help would be very appreciated. I have been using IntelliJ since 3.x and love the product - this is the first time I have ever experience anything like this.
