> Key: CXF-5994
> URL: https://issues.apache.org/jira/browse/CXF-5994
> Project: CXF
> Issue Type: Bug
> Components: JAXB Databinding
> Affects Versions: 2.7.11
> Environment: Wildfly 8.1.0.Final, JDK: 1.8.0_20-b26 64bit
> Reporter: Yannick Loth
> Fix For: 3.1.9

> java.lang.ClassCastException:
> sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast
> to java.lang.reflect.TypeVariable
> at
> org.apache.cxf.jaxb.JAXBContextInitializer.addType(JAXBContextInitializer.java:251)
> [cxf-rt-databinding-jaxb-2.7.11.jar:2.7.11]
> Happens when the type is a GenericArrayType: then the code assumes that the
> component in the array type is either a class or a TypeVariable, and the cast
> into TypeVariable fails.
> During debug sessions, I can see that the actual type is an array of a
> subtype of ParameterizedType, and obviously the code does not permit this.
> The data types were generated with Maven and cxf-codegen-plugin. The XSD is
> from Microsoft Exchange EWS (Exchange Web Service, 2006). The problematic
> type is:
> com.microsoft.schemas.exchange.services._2006.messages.ResponseMessageType[]
> This is blocking as any webservice which uses the data types of EWS fails if
> called with the standard JAXWS stack in Wildfly 8.1.0.Final.
> For the fix: maybe copying lines 234 to 243 into line 250 may be almost
> enough (simply add an else-if for ParameterizedType arrays as above, but
> adapt a little for arrays):
>
> else if (cls instanceof ParameterizedType) {
> final ParameterizedType parameterizedType =
> (ParameterizedType)cls;
> addType(parameterizedType.getRawType());
> if (!parameterizedType.getRawType().equals(Enum.class)) {
> for (Type t2 : parameterizedType.getActualTypeArguments()) {
> if (shouldTypeBeAdded(t2, parameterizedType)) {
> addType(t2);
> } } }
> Thanks
