Why do green olives come in jars and black olives come in cans?

Green olives are usually stuffed with a liquid prior to being jarred, while black olives are typically salted and dried prior to being canned. Thus, the jarred green olives need a container that will prevent leakage, while the canned black olives can withstand the higher pressure of the canning process.
