Groups changed within the same millisecond that they were selected for reaping can cause aggregators to emit duplicate messages. Use the re-fetched group (used to see if the timetamp changed) instead of the group passed in to forceClose (the group might have changed since it was selected as eligible for reaping). We still retain the last modified check because it might have been expired using timeoutOnIdle.
Spring Integration
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
