Multiline Regex with Lucene

I was trying to do a regex search with the lucene and
JavaUtilRegexCapabilities.
The code used is :
RegexQuery query = new RegexQuery(new
Term("contents","(?m)hello.*(\r[^#]*)This is to be searched.*(\r[^#]*)#"));
query.setRegexImplementation(new JavaUtilRegexCapabilities());

I verified the regex in : http://www.gskinner.com/RegExr/ [with the multi
line checked]
In lucene though there are no hits. Can you please point me in the right
direction

Content :

#
Test line should not be selected
hello
This should not work
some other lines
#
Not to be selected

Some lines
This is to be searched
Some lines
