regexp won't match

[shm]

Hello all,

\I have a problem matching a regexp, and i don't understand
why. We have a license staement which should be at the top of
every java file in our project:

and i would like to match it, so i can make some markup for it, like:

    (, "\\`\\(/\\*\\*\n   This file is part of opensearch.\n   Copyright © 
2009, Dansk Bibliotekscenter a/s,\n   Tempovej 7-11, DK-2750 Ballerup,

without even the implied warranty of\n\\)" 1 java-add-on-font-lock-license-
face prepend)

But when i try to expand the above line (after the line break it
should be three spaces and the next line of text), with just one
space it won't match.

I have used whitespace-mode to check the text, and it shows three
spaces at the beginning of the line, so I have no clue as to why
this is not workning.

Thanks in advance
