我的 JRuby on rails 应用程序在 Tomcat 6.0 上运行良好，但是当我将它部署在我公司的 JBoss 4.2.0/Tomcat 5.5 (Servlet API 2.4) 的 webfarm 上时，它失败并显示以下堆栈跟踪：

首先请注意，JRuby-Rack 在 0.9.7 版本中更改为 servlet 2.5。因此，为了在 5.5 上运行，您必须降级到 0.9.6 或更早版本。这对于 Warbler 依赖项可能有点棘手，但您可以使用config.java_libs.

至于上面的错误，我以前没见过。唯一想到的是 native/ffi 支持在某些容器中不起作用，您可能需要使用-Djruby.native.enabled=false.

可能是由低线程堆栈大小引起的。尝试通过传递-Xss16k给 JVM 来增加它。增加它，直到您找到适合您的应用程序的值。
