Pete Muir commented on WBRI-358:
--------------------------------

An obvious scalability issue will be the reflection layer, which performs extensive caching to speed up usage. It scales at O(CM) where C is the number of classes, M is the no of members in a class which reduces to O(N^2).

Options include:

* Expose to container so it provides an impl - someone elses problem
* Perform analysis, and for infrequently used operations perform direct access to class or member with no caching
* Verify that no uneeded data is stored
* Investigate lazy initialization (concurrency issues abound)
* Investigate discarding information once bean definition is built, or provide ability to create runtime version
