What you're doing seems awfully tortuous to me. Why not just use nextLine() to read your lines?
Then your pattern will be perfect for checking for blank lines (in fact, I prefer yours to Harsha's) except that you don't need the "\\n" (Scanner.nextLine() doesn't return it); and if you get two of them, you know that the next line must be the start of a new log entry.
The other problem with the way you're currently doing it is that unless you do further processing you'll get a multiline string with embedded newlines in it for your log data. While regex patterns can be set up to deal with multiple lines, they generally work best with single line input.
