第一種解決方法：
java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
這是JDK導致的問題
解決辦法：還原到F7的libX11，先寫在F8的libX11軟件
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/找到下面那兩個包，裝上
rpm -ivh libX11-1.0.3-8.fc7.i386.rpm --該軟件在
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 --該軟件在
http://rpm.pbone.net/index.php3?stat=26&dist=53&size=680199&name=libX11-devel-1.0.3-8.fc7.i386.rpm
最后加上下面兩行到/etc/yum.conf文件中，以防止更新linux的時候又恢復到新版本
# List of packages to exclude from updates or installs
exclude=libX11 libX11-devel
第二種解決方法：
首先看報錯的信息：

已放棄

這個問題，官方解釋這是由于使用了XCB而不是LibX的緣故，關鍵就在于assert時，Lock問題。一種解決方案是回去使用libx，另一種則是去掉assert時的檢查。今天在網(wǎng)上看到有人用F9了，突然想，是不是官方有對xlib的解決方案呢？
所以update一下：
[root@icnote eclipse]# yum --enablerepo=development update libxcb --注意這里，這是安裝libxcb-devel-1.1-1.fc9.i386.rpm軟件
其實也可以本地安裝：
[root@icnote eclipse]# yum localinstall libxcb-devel-1.1-1.fc9.i386.rpm --該軟件在
http://rpm.pbone.net/index.php3?stat=26&dist=32&size=127269&name=libxcb-devel-1.1-1.fc9.i386.rpm
