https://build.spring.io/browse/INT-MASTER-1038 When we don't provide an `output-processor` for the `<barrier>` definition, the new logic in the `IntegrationNamespaceUtils.constructAdapter()` ends up with the `null` injection into the `BarrierMessageHandler` ctor. From here there is no guarantee which ctor will be selected: ``` BarrierMessageHandler(long timeout, MessageGroupProcessor outputProcessor) ... BarrierMessageHandler(long timeout, CorrelationStrategy correlationStrategy) ``` From reflection perspective they both are equal and there is no predictable outcome which is is going to be selected. Looks like on Windows and OSX, the second (expected) is selected, but on Linux it is the first one. * Fix `IntegrationNamespaceUtils.injectCtorWithAdapter()` do not inject `adapter` in to the target ctor if it is `null`. This way the `BarrierMessageHandler(long timeout)` ctor is selected without any ambiguity
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
