Why are green olives packed in jars and ripe olived packed in cans?

Black olives, technically known as black ripe olives, come in a can because they actually cook them in the can. Olives go in, a brine or juice is added, cans are sealed and they then go into a continuous cooker. Glass simply can't hold up to the intensity of the cooking process.
Green olives, meanwhile, are processed differently — they're pasteurized but not cooked, then put in jars with brine added.
