grails run-app returns a strange case of "context initialization failed"

Question

I'm using grails 2.0.0.M1 with few plugins (spring-security-core-1.2.1, spring-cache-1.3.1). No problems cleaning and comipling the application, only running it.

This is the result executing "grails run-app --stacktrace":

ERROR [org.springframework.web.context.ContextLoader]: Context initialization failed

Answer 1

Solved: I was retrieving from a service the value of a property (still) not declared in the Config.groovy (as a static Integer variable, explained the casting exception).

Hope this helps someone else.
