["James Carman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12895901#action_12895901 ]

-----------------------------------------------------------

Why not just do this:

private static final Pattern WHITESPACE_BLOCK = Pattern.compile("\\s+");

public static String normalizeWhite(String input)
{
    if(input == null)
    {
        return input;
    }
    return WHITESPACE_BLOCK.matcher(input.trim()).replaceAll(" ");
}

      was (Author: jwcarman):
    Why not use String.replaceAll("\\s+", " ")?
