/**
 * Context provider registered via resource path lookup. When module is on classpath this provider will be used to instantiate
 * Citrus.
 *
 * Provider creates a CitrusContext that is backed with a Spring application context. Provider caches the last application context
 * that has created a context. When very same application context creates another CitrusContext use the cached instance. This
 * caching should give us some performance improvements and less instance duplications.
