I wrote a custom shiroEnvironmentClass which sets up the necessary
configuration programmatically, and it sped up the startup from timing out
at around 60 seconds to finishing in less than a second

org.apache.shiro.web.env.EnvironmentLoader initEnvironment: Shiro
environment initialized in 320 ms.

I still don't know why the reflection-based builder was so slow in the App
Engine environment, while other users did not see this issue.

Thanks for the pointers,

Geir
