HTTP2 Server Agent may encounter class cast exception
When using the HTTP2 Server Agent with the Open API Profile, certain yaml specification file, for example TS29520_Nnwdaf_AnalyticsInfo.yaml, will cause the HTTP2 Server Agent to throw a class cast exception bug during runtime.
This is specific to yaml files that utilises 'allOf'. The behaviour exhibited by 'allOf' is where it takes an array of object definitions that are used for independent validation. However, it together is composed as a single object.
