Sample use cases: 1. Perform multiple operations, some failed due to different reasons. Return a CompositeException for the failed ones. 2. Do a validation on some input. I want to collect all different failures, I can throw a CompositeException. 3. In some cases the exception had occurred earlier, and we want to throw all such exceptions. For example failures caused by Java Agent, some java agents store such failures. During actual execution I want to throw all such exceptions.
Basically any such scenarios where there are multiple causes for failure and I want to throw all of them.
