When a simple MessageHandler is referenced from a `<service-activator/>`, it is wrapped in an anonymous AbstractReplyProducingMessageHandler to facilitate proper handling of the `<request-handler-advice-chain/>` and so that normal 'produced no reply` messages are logged. Previously, this caused 2 MBeans to be exposed, one for tha actual handler; one for the wrapper. This added more stack frames between the dispatcher and the handler (because 2 sets of statistics were captured). The root cause was that the MBean exporter was not aware of the relationship between these objects. https://jira.springsource.org/browse/INT-3186 Add code to the IntegrationMBeanExporter to suppress adding metrics to the wrapper. This involves detecting that it is a wrapper and not exposing it as an MBean and, when matching handlers with endpoints, checking that the wrapped handler is the actual handler for the endpoint. Update test to reflect the reduced number of stack frames between the dispatcher and handler. Also add tests to verify the detection of multiple references to the same ARPMH.

Spring Integration
Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
