Jruby - Foreman Gem not running

Question

我正在運行一個JRUBY應用程序。跌跌撞撞翻過叫福爾曼一個偉大的寶石： https://github.com/ddollar/foreman

但是我發現 - 即JVM不支持分叉：

這是一種恥辱，因爲我喜歡運行福爾曼的想法。有誰知道上述問題，或者替代周圍的工作，將一個JRUBY環境中運行

Answer 1

由於這種寶石的創作者的真棒工作，這是目前在JRuby中

https://github.com/ddollar/foreman

可用

在JRuby中運行良好1.6.6

Answer 2

另外幾個選項是RVM包裝和保護::流程所列出的位置：http://www.without-brains.net/blog/2011/09/21/using-foreman-to-run-jruby-with-rvm-and-mri/
