TLDR

Generation of the Dmaap events is happening right before committing the transaction. But, it has to happen after committing the transaction.

At present, generating events and sending notification events are tightly coupled within the "process" method of "HttpEntry.java" class in aai-core. The code has to be refactored to make them loosely coupled and in turn to ensure that generation of events and sending notification events happen only after the present transaction is committed to data store (JanusGraph / Cassandra).
