This commit updates Spring Integration to depend upon Spring 4, making use of the message types that have moved from Spring Integration into Spring's new spring-messaging module. The default message converter no longer supports conversion of a message that is null, throwing an IllegalArgumentException if an attempt is made to convert null. Furthermore, GenericMessagingTemplate does not support sending null, again throwing an IllegalArgumentException. Previously, MessagingTemplate had no-oped an attempt to send null. ConcurrentAggregatorTests and AggregatorTests both had a single test that was specifically testing the behaviour of an aggregator that returns null for its message. These tests have been removed. CorrelatingMessageHandlerTests have been updated to specify some additional behaviour for its mocks so that null messages are not returned. These are the only functional changes that have been made. All other changes are simply for moving to the repackaged and/or renamed types. In the move to being part of core Spring, a number of constants and header accessor methods have moved from MessageHeaders to MessageHeaderAccessor. This commit continues this pattern for the enterprise integration headers that are specific to Spring Integration. A new class, EiMessageHeaderAccessor, has been created. This class provides constants and methods for working with SI-specific headers. The main code and tests have been updated to use this new class.

Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/SpringSource/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
