compiler-errors

I have the following code:

    String serviceType;
    ServiceBrowser tmpBrowser;
    for (String playerName: players) {
        serviceType = "_" + playerName + "._tcp";
        tmpBrowser = BrowsersGenerator.getBrowser(serviceType);
        tmpBrowser.browse();
        System.out.println(tmpBrowser.getStatus());
    }       
    System.out.println(tmpBrowser.getStatus());

The compiler complains about the last line. It writes "variable tmpBrowser might not been initialized". If I comment the last line the compile does not complain.

Why won't xattr PECL extension build on 12.10?

I was using the xattr pecl extension in 12.04 (in fact, I think since 10.04) without problem. Not surprisingly, I had to reinstall it after upgrading to 12.10 because of the new version of PHP. But now it fails to build, and I can't figure out why. Other PECL extensions have built fine. And I have… >>> More
