JIRA: https://jira.spring.io/browse/INT-4105 Fixes GH-1888 The lock in Redis can be expired in between `obtain()` calls. So, even if we return a new lock instance, the old one must clear properly. * Add `lock.unlock()` to the `obtain()` if the case of expiration in Redis. * Add `warn` for the exception on the `lock.unlock()`. We don't care about error here and just proceed to a new instance. **Chery-pick to 4.3.x** Remove the lock reference from `weakThreadLocks` as well Add `registry.setUseWeakReferences(true);` to test-case * Add assert for `lock.unlock()` in case of expiration * Add `UUID.randomUUID()` for the registry key to avoid cross-talking during concurrent builds, e.g. on the CI server https://build.spring.io/browse/INT-MASTER-352 This is actually a fix for the JIRA: https://jira.spring.io/browse/INT-4083
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
