I can now confirm that this a serious Java bug. 

I discovered this by doing the following:

I downloaded the ant source and I discovered that the original file is copied to
a temp file and then that temp file is renamed to the original file. So in
short, the original file is copied, edited and then overriden. So I decided to
do some experimenting. I moved my source code from 'My Documents' directory
which is located under the Document and Settings directory and moved it into
c:\Project. Now the replaceregexp task works.

Apparently Java doesnt know to handle files like this:
C:\Documents and Settings\User\My
documents\Projects\MyApp\projects\dao\src\conf\hibernate.properties

I tried the following:
if (!new File("C:\\Documents and Settings\\User\\My
documents\\Projects\\MyApp\\projects\\dao\\src\\conf\\hibernate.properties").delete())
    System.out.println( "Could not delete" );
else
    System.out.println( "Could delete" );

As output I get the message 'Could delete' and the file is deleted. This makes
me beleive that there is something totally messed up in Java. Deleteing a file
in one instance doesnt work but manually creating a File object pointing to that
file and then deleting it will work.

This isnt a Ant issue but a Java issue.
