为什么加载 jruby 的可执行 jar 不能在名称中包含空格（例如 Program files）的文件夹下运行？

Question

我有一个加载 jruby 的可执行 jar。安装程序将 jar 和一些预打包的 jar 库（包括完整的 jruby 和一些 gems）放入安装位置。

一切工作正常，除了在 Windows 中，当 jar 安装到名称中包含空格的文件夹中时。当 Jruby 遇到来自 jar 打包的 gem 之一的简单“require”时，它会失败（状态机 gem 中的“require singleton”，如果这很重要的话）。

这本来不是什么大问题，但我需要 jar 从程序文件下运行。希望有人已经解决了这个问题:)

这可能是一个错误。您使用什么软件来创建可执行 jar？什么版本的 JRuby？我们过去已经处理过带有空格的文件名错误，但肯定还可能存在其他错误。您可以在 http://bugs.jruby.org 提交错误吗？谢谢。
