This seems like a lot of copy+pase code. Please just wrap a Java JDK ArrayDeque.

There is already a BlockingDeque interface in the Java JDK, so this class name is kind of confusing and it does not implement the interface.

I'm not sure how useful decoration will be. Might be more helpful to have an ArrayBlockingDeque class.

I found someone raised that adding support for deque interface in Collections.(https://issues.apache.org/jira/browse/COLLECTIONS-563)
(https://issues.apache.org/jira/browse/COLLECTIONS-564)
This makes sense so I wrote some code to make a try. I want to know if my implementation is appropriate, if my PR is merged or given comments and suggestions, I would be happy to finish the rest of the work.
