JavaDoc bug about Pattern.compile("\\")

Reading the evaluation from Bug 4783892 it would appear the JavaDoc is wrong.
I am looking at the most recent JavaDoc: http://download.java.net/jdk6/docs/api/java/util/regex/Pattern.html and it only shows \\ for the backslash character instead of \\\\ as the evaluation says it should.
