JIRA: https://jira.spring.io/browse/INT-4202 The `StoredProcOutboundGateway` uses `MessageBuilder` directly for procedure result without any conditions. If procedure result is `null`, `MessageBuilder.withPayload` throws `java.lang.IllegalArgumentException: payload must not be null`. * Since the super `AbstractReplyProducingMessageHandler` class takes care about `null` reply properly via its `requiresReply` property and really uses `MessageBuilder` for reply, just fix `StoredProcOutboundGateway` to return procedure result as is from the `handleRequestMessage()` implementation * Fix some typos and code style * Increase some JDBC tests performance changing `Thread.sleep()` solution to proper `PollableChannel.receive()` or iterations over expected result **Cherry-pick to 4.3.x** Update `@Copyright` to 2017 Make `StoredProcOutboundGateway` as `requiresReply = true` by default Revert `setRequiresReply(true)` change Specify `setRequiresReply(true)` only if `expectSingleResult == true` and `setRequiresReply()` hasn't been called explicitly
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
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
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
