Dependency injection (Spring / Guice) initialization control

[jpeffer]

The use of the ClassInitializer mechanism to initialize a dependency injection framework leads to the context being initialized multiple times even within a given specification. Is there a way to perform this initialization more globally, so that the context can be shared? This would help to avoid the performance penalty of initialization, among other potential benefits. Having something like a SuiteInitializer or SpecificationInitializer, would help to provide more control over this process. My initial need is to initialize the context once, but more granular control would be welcomed as well.
