getAndUnwrap

public static <K,V> V getAndUnwrap(com.google.common.cache.Cache<K,V> cache,
                                   K key,
                                   java.util.concurrent.Callable<? extends V> loader)

Same as Cache.get(Object, Callable) but in case of exceptions unwraps the ExecutionException layer.

This is useful if the loader can throw "special" exceptions like ProcessCanceledException in the IDE.
