We don't fear calling the factory twice for benign races, as the distinct constructor factory instances are behaviorally the same. The true issue lies in the double getfield operations: Java memory model doesn't require the second read to happen-after a write reflected in the first read, so return this.genericInfo may return null while this.genericInfo == null evaluates to false, in case genericInfo is initialized lazily by another thread.
