/**
* Base class for exceptions that occur within a flow while it is executing. Can
* be used directly, but you are encouraged to create a specific subclass for a
* particular use case.
*
* Execution exceptions occur at runtime when the flow is executing requests on
* behalf of a client. They signal that an execution problem occured: e.g.
* action execution failed or no transition matched the current request context.
* An execution exception does not indicate a flow definition problem, a
* {@link FlowArtifactLookupException} is used for that.
