Hi Angela, Off the top of my head form looking at your specs...
I would guess to say based on my experience with java which dates back to 1998... no. 64bit should accommodate 32bit apps forward revs should accommodate previous revs. byte codes that is I say go for it Funny when I think about my beginning old days in java... write once run everywhere ... was the claim to fame... but I extended it... write right once and run everywhere your java code should be platform safe
