我安装了 Lubuntu 12.10 64bit 和 Eclipse Juno Distribution。如果我切换到 Preferences- Checkstsyle 并在那里配置（打开 checkstyle 配置）我得到以下异常：
org.eclipse.swt.SWTError: No more handles [MOZILLA_FIVE_HOME='/home/user/Development/Tools/firefox18.0.2'] (java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:

我在网上找到了很多关于这个问题的帖子，但没有一个可以帮助我。我到底该怎么做？目前我只在 home/user 的 .profile 中设置了 MOZILLA_FIVE_HOME 路径。
我目前已经安装了我在 PATH 和 JAVA_HOME 中提到的 Oracle JDK 1.7。
能得到你们的帮助将不胜感激。
问候马克
