Your active platform: JDK_1.6, but the corresponding property "platforms.JDK_1.6.home" was not found in the project properties files

Question

I am Java noob (but have been programming for another 25 years and have been working with OO languages ​​from day one).

Suddenly, I started getting this error:

Your active platform is: JDK_1.6, but the corresponding property "platforms.JDK_1.6.home" is not found in the project properties files. 

Not sure what caused this condition, and not sure what Java is asking me to do. I work in NetBeans IDE. The last thing I tried to do was add my resources (images) to the project.
