When a plane gets up to 35,000 feet, the pilots will adjust the cabin pressure to the equivalent of 6,000 to 8,000 feet in the air. The change in pressure is the reason why your ears feel so weird up at altitude, but it can also be why your sealed jars crack and leak. Unlike air, liquid can't expand. So when cabin pressure changes, the air inside the jar also balloons up and pushes outward. If the container is too weak, it's going to pop.
