The UI and terminology of the Libraries properties dialog is pretty confusing.

The Help button on that dialog will give you a fair bit of info.

The Compile-time library list may be a subset of the Run-time library list.

Consider this situation...

You have source code that imports classes from on a library 'widgets.jar'. The class files in widgets.jar reference symbols from the jar file 'xml.jar'. If your source code does not import classes from xml.jar, you could define the Compile-time libraries list to contain just widgets.jar.

When you try to run your project, you will probably need to include xml.jar in the Run-time libraries list to prevent ClassNotFoundException's.
