无法启动Jenkins

Question

我在Ubuntu 12.04中安装了Jenkins，我将端口改为8888。

root@kandabap-ThinkCentre-M91p:/etc/default# dpkg -l | grep jenkins
ii  jenkins                                1.518                                   Continuous integration system written in Java

root@kandabap-ThinkCentre-M91p:/etc/default# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.6.3

当我启动Jenkins时，它会保持一段时间的活动，然后就会消失。

日志显示，

 18/06/2013 4:08:39 p.m. winstone.Logger logInternal

期待专家的帮助，让jenkins在我的机器上运行。谢谢。

我想和SEVERE: Failed to initialize Jenkins一样。

根据初始响应，这是由使用'gcj‘引起的。解决方案是使用OpenJDK或Oracle JDK。
