> {{FromClasspathEntryClassInformationProvider}} is attempting to verify (eagerly) whether the given MainClass is on the user classpath. However, it doesn't handle cases where the main class is inside a nested jar.
> We actually don't need this check at all since {{PackagedProgram}} is already doing it while attempting to load the main class. Having this once should be enough.
