No. I use whiteface as Jolson was caucasian,

Seriosuly though, I really don't know what Jolson's blackface intention was really about, but after having seen the movie 'The Jazz Singer', I'm more convinced that his blackface performance was not meant as racist, but instead his way of honoring the great Bill Bojangles Robinson:
