With the `time-source` in Spring Cloud Stream we noticed that first two items have the same (or close) value when the `time-supplier` is used with the reactive output channel. Turns out the `contactMap()` with `prefetch == 1` asks two upstream elements immediately not waiting for a completion for the fist one. This way we were not able to update `triggerContext` for the proper `lastCompletionTime` * Change `AbstractPollingEndpoint` to `prefetch = 0` for the "fair" upstream request * Verify the behavior with the new `ReactiveInboundChannelAdapterTests.testTimeSupplierConsistency()` * Mark `ReactiveInboundChannelAdapterTests` as `@LongRunningTest` since it is now pretty long waiting for all the 3 dates to verify * Fix `InboundChannelAdapterAnnotationPostProcessor` to properly register `MethodInvokingMessageSource` when we have more than one `Supplier` with the `@InboundChannelAdapter` in the same configuration class

Please see our Security policy.
Checking out and Building
To check out the project and build from the 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 an available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew publishToMavenLocal
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
