the request will be considered "handled" by the controller method.

Tiles 3 has modified packages and classes as well as additional
dependencies, notably "tiles-request-api", which is a request/response
abstraction independent of Servlet and JSP APIs.

In order to have both Tiles 2 and Tiles 3 integrations, the source for
the Tiles 3 integration is in a separate project spring-webmvc-tiles3.
The build process merges the compiled Tiles 3 integration classes into
the spring-webmvc module so in effect it contains both the Tiles 2 and
the Tiles 3 integrations.

Modify ReflectivePropertyAccessor so that it no longer considers
bridge methods when finding getters or setters. This should help
to prevent subtle errors that can occur when particular JDK
implementations happen to return bridge methods before non-bridge
