It's for holding code generated by annotation processors.

Thanks Laurence. Does that mean this folder is auto generated only for projects using annotations? – Fracture

That I do not know, but I suspect it may be true as none of my Eclipse projects contain this folder. – Proterozoic

This isn't necessarily needed for Annotations themselves. This folder is created if and only if you have "Annotation Processing" enabled on the project. See Project Properties > Java Compiler > Annotation Processing. You can probably disable it if you have no classes implementing com.sun.mirror.apt.AnnotationProcessor. – Eucharis

I don't have "Annotation Processing" enabled, try to remove it, from the Build Path, from the project, but then it is again generated automatically. I do not use Annotations either – Robi
