我安装了Lubuntu 12.10 64bit和Eclipse Juno Distribution。如果我切换到Preferences- Checkstsyle并在configure（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:

我在网上发现了很多关于这个问题的线索，但没有人可以帮助我。我到底要做什么？目前我只在家庭/用户的.profile中设置了MOZILLA_FIVE_HOME路径。
我目前安装了Oracle JDK 1.7，我在PATH和JAVA_HOME中提到过。
非常感谢能得到你们的帮助。

我在Fedora 19（64位）上遇到了类似的问题。我通过以下步骤解决了这个问题：
1. $ sudo yum install libwebkitgtk*
2. Restart Eclipse
