How to check if a folder exists
<p>I am playing a bit with the new Java 7 IO features, actually I trying to receive all the xml files of a folder. But this throws an exception when the folder does not exist, how can I check if the folder exists with the new IO? </p>

<pre><code>public UpdateHandler(String release) {
    log.info("searching for configuration files in folder " + release);
    Path releaseFolder = Paths.get(release);
    try(DirectoryStream&lt;Path&gt; stream = Files.newDirectoryStream(releaseFolder, "*.xml")){

        for (Path entry: stream){
            log.info("working on file " + entry.getFileName());
        }
    }
    catch (IOException e){
        log.error("error while retrieving update configuration files " + e.getMessage());
    }


}
</code></pre>
