fix #598, #592 (alternative implementation to #594 ) - set isCoalescing property to true on XMLInputFactory since in a certain environment the underlying stax implementation was breaking up one XML text node into multiple because the HTTP stream was chunked, and this was breaking parsing of the JSON in that text node

(cherry picked from commit 1bfe12a)
