带有 Xvfb 插件的 Jenkins：空构建时出现 "Prefix string too short" 错误

Question

我创建了一个空项目，检查 "Start Xvfb before the build, and shut it down after."，然后构建因错误而失败。

出了什么问题？

Ubuntu 服务器 14.10
詹金斯 1.597
xvfb 插件 1.0.13
Xvfb 可执行文件路径：/usr/bin/Xvfb

Xvfb Jenkins 插件版本 1.0.15 修复了这个问题。另见 https://issues.jenkins-ci.org/browse/JENKINS-26505。
