Mule DevKit - transformer / Cannot load application's classes - maven

Question

I am implementing a Connector with a Transformer in Mule DevKit (3.7 - Latest). I am successful in building (maven) and installing in Studio. The functionality of the Transformer is to load the class that is being passed as an argument (from payload) in runtime and access its methods to set some objects and construct a message format specific to a 3rd party protocol. When I run the application, it starts and deploys successfully; but getting Classnotfound exception. Kindly suggest/recommend a solution.
Code in my transformer class; where wsClassName is being passed as org.aa.bb.cc.MemberSearchRequestInfo (refer logs)
woClassObject = Class.forName(wsClassName).newInstance();
Mule project has the MemberSearchRequestInfo class in the specified package under src/main/java
Below is the logs.
