Bulkhead and Backpressure Pattern with Java EE 7

What is Bulkhead Pattern?

https://en.wikipedia.org/wiki/Bulkhead_(partition)

"Isolate elements of an application into pools so that if one fails, the others will continue to function.

This pattern is named Bulkhead because it resembles the sectioned partitions of a ship's hull. If the hull of a ship is compromised, only the damaged section fills with water, which prevents the ship from sinking."
