NoClassDefFoundError after renaming a package

Question

I am writing a simple application using Netbeans; when creating a new Java project, I renamed the automatically created package from oldpackageto newpackageusing the Netbeans rename function (i.e. using Refactor> Rename ...)

When I run the program, I get this exception:

    java.lang.NoClassDefFoundError: oldpackage/Main
Caused by: java.lang.ClassNotFoundException: oldpackage.Main
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: oldpackage.Main.  Program will exit.
Exception in thread "main" Java Result: 1

I did some Googling but couldn't find the obvious solution - can anyone help?
