JIRA: https://jira.spring.io/browse/INT-4430 When Iterator-based `FileSplitter` splits the file, and an exception throws in downstream flow (in the same thread), the exception propagates to the caller leaving underlying file reader opened. This commit changes `AbstractMessageSplitter` the way, that, when any exception happens, if Iterator implements `java.io.Closeable`, its `close()` method will be called before propagating exception. Also `FileSplitter`'s underlying iterator implements `Closeable` now. * Make `CloseableIterator` to follow `Closeable` contract. Now `CloseableIterator.close()` declares `IOException` and can be used as base interface for `FunctionIterator`. * Adjust tests. Adjust tests to reflect the fact that we call `close()` on the reader one more time in the end of iterator. **Cherry-pick to 5.0.x and 4.3.x**
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
