Used to annotate SPI provider contracts recognized by Jersey (in addition to the JAX-RS providers). All proprietary Jersey extension APIs are annotated with the @Contract annotation. 

Similarly, any custom (i.e. not JAX-RS or Jersey) extension provider contract must be annotated with this
annotation otherwise concrete service classes implementing the provider contract would not be recognized
and treated as extension service provider by Jersey runtime.
