Linux Lubuntu Eclipse Checkstyle SWT 错误

Question

我安装了 Lubuntu 12.10 64 位和 Eclipse Juno Distribution。如果我切换到 Preferences-Checkstsyle 并进行配置(打开 checkstyle 配置)，则会出现以下异常:

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: 
    /home/user/Development/IDE/eclipse/configuration/org.eclipse.osgi/bundles/626/1/.cp/libswt-mozilla-gtk-4234.so: libxpcom.so: wrong ELF class: ELFCLASS32

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。我究竟需要做什么？目前我只在 home/user 的 .profile 中设置了 MOZILLA_FIVE_HOME 路径。

我当前已经安装了 Oracle JDK 1.7，我在 PATH 和 JAVA_HOME 中引用了它。

很高兴能得到你们的帮助。

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:
