See SO for more info: https://stackoverflow.com/questions/64456946/handle-exceptions-errors-other-than-messagingexception-ie-other-error-excepti In the versions before `5.2.x` the `Error` was wrapped to the `MessagingException` in the `AbstractRequestHandlerAdvice` and this one was handled properly on the gateway level with its `errorChannel` configured * Fix `MessagingGatewaySupport` to catch all the `Throwable` and try to send them as `ErrorMessage` to the `errorChannel`. Otherwise unwrap returned `MessagingException` and re-throw an `Error` as is to keep the current behavior for non-handled exceptions * Do not wrap `Error` into a `MessagingException` and re-throw as is if there is no `errorChannel` **Cherry-pick to 5.3.x & 5.2.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
