Just FYI, depending on what source you use, you can identify somewhere between 300 and 600 species of the genus Quercus that are all oak, so your categorization of the wood as "oak" is not as helpful as you might think.
Now, granted, you can't tell most of those species apart outside of a lab (unless you have the tree itself and are an expert on bark and leaves and such), but still, it's common to at least distinguish among red oak, white oak, and live oak.
Now all of that was just to prove what a smart-ass I am (as TT and others will gleefullly confirm), but is pretty much irrelevant to your question since as far as I know all of the oaks respond poorly (they stain) in the presence of ferrous metal combined with moisture).
What do they do around non-ferrous metals? As far as I know, nothing. It's the iron that causes the stain-inducing reaction.
So all of that was my roundabout and long-winded way of saying "not 100% positive but I'm pretty sure you won't have a problem with zinc".
