Answer 1

首先要注意JRuby的機架改爲Servlet 2.5的爲0.9.7發佈。所以爲了在5.5上運行，你必須降級到0.9.6或更低版本。 Warbler依賴關係可能有點棘手，但您可以使用config.java_libs手動調整Warbler配置文件中的jar。

至於上面的錯誤，我以前沒見過。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將其禁用。

Answer 2

org.jruby.rack.RackInitializationException: stack level too deep 

可能是由低線程堆棧大小造成的。嘗試通過將-Xss16k傳遞給JVM來增加它。增加它直到你找到一個對應用程序無害的值。
