Performance related fix from David J. Strite. Thanks David!!

The AbstractContext.properties map starts with the default size of 16. Enough properties are added to the message context to resize and rehash the map twice during a request. Each time a HashMap is resized, it's doubled. Setting the initial size to 64 prevents the resizing.
