Solution

That is an icon 'decorator'. These are added by the view using the Eclipse decoration manager.

That specific decorator is added when there are warning markers on resources in the project.

Markers are created by plug-ins using the createMarker method of IResource (usually its derived interfaces IFile, IFolder or IProject).
