Golems Become Hostile When Trading With Villagers

So I have noticed in my created village with automatically spawning 4 Golems is that they would become hostile towards me 1 by 1. I have noticed that they may be neutral at first, but when I attempt to trade with certain villagers, they become hostile towards me. The Golems would become hostile 1 by 1, and the hostility doesn't reset. Sometimes if I run away, they will become neutral again, but once I attempt to trade with certain Villagers, they become hostile once more. Killing them or dying does not reset this. Please fix this. Thank you. I am playing on Minecraft Server 1.8.1

I have using Java 7/ Java 8.
