java.util.regex - combining paragraphs separated by blank line

[David]

I need to write a regular expression to group lines of text separated
by a blank line.

Ex.

Input:
line1
line2
line3

line 4
line 5

line 6

I tried turning on the MULTILINE and DOTALL flags and used the
following pattern:
(.+?)^$

which is close but prepends a newline to the 2nd and subsequent calls
to Matcher.find().

The first line of every paragraph is the same, if that helps.

Regex's are cool, but frustrating....

Regular expression that matches a blank line is ^$
_Mastering Regular Expression_ by Friedl from O'Reilly is a good book.
