      Security Level: Public (Viewable by anyone)
          Components: spring
    Affects Versions: 2.1

We have dependency of GridResourceBasicInjector class in GridSpringResourceContextImpl.
This cause issues when core and spring jars are loaded with different classloaders.

GridSpringResourceContextImpl tries to create GridResourceBasicInjector explicitly that has package visibility and located in different jar.

Possible solution is to have static util method that will has return type GridResourceInjector and return GridResourceBasicInjector instance.
