    Description

      Java BB.allocateDirect() will allocate native memory out of the JVM and will help reducing the GC pressure in the JVM with a large Cache.
      From some of the basic tests it shows around 50% improvement than doing a normal Object cache.

      In addition this patch provide the users an option to choose BB.allocateDirect or store everything in the heap.
