java.util.ConcurrentModificationException when the MI server attempts to undeploy the faulty carbon applications.
The stack trace is as follows.
ERROR {CappDeployer} - Error while deploying carbon application wso2mi4.1.0.57/repository/deployment/server/carbonapps/DisplayDevicesAPIComr_1.0.0-SNAPSHOT.car java.util.ConcurrentModificationException

The exception occurs when it's iterating over the swaggerTable using an iterator obtained from swaggerTable.keySet().iterator(). However, it's modifying the swaggerTable while iterating over it by calling swaggerTable.remove(name) within the loop. This has led to a ConcurrentModificationException because the iterator detects that the collection has been structurally modified during iteration.
