CTD modeling of interfaces with parameterized types

[sinha108]

Describe the bug

Handling of interfaces with parameter types fails during CTD modeling:

Error:    CTDModelingTest.testGenerateModelsAndTestPlansForAllClasses:97->compareModels:129 expected:
<[willDecode(Ljava/lang/String;)Z, decode(Ljava/lang/String;)Ljava/lang/Object;]> but was:<[willDecode(Ljava/lang/String;)Z, decode(Ljava/lang/String;)Lcom/ibm/websphere/samples/daytrader/web/websocket/ActionMessage;]>
