第一种解决方法：
java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
这是JDK导致的问题
解决办法：还原到F7的libX11，先写在F8的libX11软件
rpm -e --nodeps libX11-1.1.3-4.fc8
rpm -e --nodeps libX11-devel-1.1.3-4.fc8
再到
http://rpm.pbone.net/找到下面那两个包，装上
rpm -ivh libX11-1.0.3-8.fc7.i386.rpm --该软件在
http://rpm.pbone.net/index.php3?stat=26&dist=53&size=814567&name=libX11-1.0.3-8.fc7.i386.rpm
rpm -ivh libX11-devel-1.0.3-8.fc7.i386.rpm --该软件在
http://rpm.pbone.net/index.php3?stat=26&dist=53&size=680199&name=libX11-devel-1.0.3-8.fc7.i386.rpm
最后加上下面两行到/etc/yum.conf文件中，以防止更新linux的时候又恢复到新版本
# List of packages to exclude from updates or installs
exclude=libX11 libX11-devel
第二种解决方法：
首先看报错的信息：

这个问题，官方解释这是由于使用了XCB而不是LibX的缘故，关键就在于assert时，Lock问题。一种解决方案是回去使用libx，另一种则是去掉assert时的检查。今天在网上看到有人用F9了，突然想，是不是官方有对xlib的解决方案呢？
所以update一下：
[root@icnote eclipse]# yum --enablerepo=development update libxcb --注意这里，这是安装libxcb-devel-1.1-1.fc9.i386.rpm软件
其实也可以本地安装：
[root@icnote eclipse]# yum localinstall libxcb-devel-1.1-1.fc9.i386.rpm --该软件在
