Not sure renaming to WaSP will actually mean much.
Sorry, but there's no renaming going on. The Jakarta Server Pages will remain to be called Jakarta Server Pages.
This just concerns the name for an implementation.
Spec: Jakarta Faces
Impl: Mojarra, MyFaces
Spec: Jakarta Security
Spec: Jakarta Server Pages
Impl: Jasper (part of Tomcat), WaSP (new name for previously unnamed impl folder)
