NetBeans code completion shows the old names of classes that were renamed

Question

In NetBeans 6.7.1, I had a Java project in which I renamed some classes. After renaming them, the code completion showed the old names of the classes and not the new names. When I would build a project that depended on this project, I noticed it would even create the .class files for the old classes. If I deleted the renamed classes and created them from scratch, the issue persisted. I could find no references to the old names of the classes in my project folder using grep. I would also get runtime errors where I had code using the new class names. When I would build the project though, it was successful. What could be the issue?

After trying many different things, deleting my NetBeans cache folder and restarting NetBeans was the only remedy for the problem. On Windows, the cache folder is located at C:\Documents and Settings\USERNAME\.netbeans\6.7\var\cache. This seems to be a bug in NetBeans.
