linux下启动spoon提示Could not load SWT library

问题描述：

linux下启动spoon时提示错误

# ./spoon.sh
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
        no swt-pi-gtk-4332 in java.library.path
        no swt-pi-gtk in java.library.path
        Can't load library: /root/.swt/lib/linux/x86_64/libswt-pi-gtk-4332.so
        Can't load library: /root/.swt/lib/linux/x86_64/libswt-pi-gtk.so
        /root/.swt/lib/linux/x86_64/libswt-pi-gtk-4332.so: libXtst.so.6: cannot open shared object file: No such file or directory

解决办法：

linux仅按照核心模块，未安装图形界面，需要手工安装图形模块，并重新远程登录系统：

yum -y install gtk2 libXtst xorg-x11-fonts-Type1
yum -y groups install "GNOME DESKTOP" "Graphical Administration Tools"
