> The constructor for {{AllocatedEvaluatorBridge}} needlessly loads the class hierarchy from disk:
> {code}
> public AllocatedEvaluatorBridge(final AllocatedEvaluator allocatedEvaluator, final String serverInfo) {
> ...
>     clrClassHierarchy = Utilities.loadClassHierarchy(NativeInterop.CLASS_HIERARCHY_FILENAME);
> ...
> }
> {code}
> We could follow the approach taken in [REEF-310] and augment the factory to also produce the {{AllocatedEvaluatorBridge}} to prevent this from happening.
