    String pattern = "^[0-9abcdef]{32} {2}[\\w]*";
    Assert.assertTrue( Pattern.compile( pattern ).matcher("18742594636e452218b9b3bca10c07f2  dashboard.xml").matches() );

Use .* instead of [\\w]*

String pattern = "^[0-9a-f]{32}[ ]{2}.*$";
                                     ^---two spaces and after this, any string of characters
