I have a WSDL-first web service that is using CXF 2.7.6, using Wrapped-style.
The getState web service interface method returns an int value. However,
when I call the web service from my CXF client code, I usually get a
ClassCastException with the message 'can't cast a GetStateResponse object to
an Integer'. I say usually because the ClassCastException does not occur
every time I make the web service call. I also intermittently get a similar
ClassCastException on calls to other methods in the web service interface.
I'm able to work-around the issue by assigning the return value to an Object
and then determining its type and handling it accordingly, but this is a
definite hack and I'd like to find the root cause of the issue. Below are
excerpts from the WSDL, schema and interface class.
