Can't reallt establish any statistically significant difference either way here, neither on score or allocations. 

So just to understand this a bit better I instrumented to see how common that condition is and it seems that when  `tree.getTag() == Tree.PACKAGEDEF` then `tree.annotations` is never empty. At least in this benchmark. Perhaps the case when there are no annotations are skipped earlier?
