----------------------------------

             Summary: Exception during maven cxf-java2ws-plugin:2.7.1:java2ws when XmlAdapter
has generic parameter
                 Key: CXF-4708
                 URL: https://issues.apache.org/jira/browse/CXF-4708
             Project: CXF
          Issue Type: Bug
          Components: Tooling
    Affects Versions: 2.7.1
         Environment: Maven 3.0.4, cxf-java2ws-plugin 2.7.1
            Reporter: Jakub Štiller


Following exception is thrown when generate WSDL from Java Code. I was able to debug the code
and found that problem is that implementation of the XmlAdapter contains generic typed class.

Eg. Following XmlAdapter declaration does not work.
{code}
public class MappedListXmlAdapter<K, V> extends XmlAdapter<JaxbHashMapList<K,
V>, MappedList<K, V>> {
{code}
but the declaration without generic works:
{code}
public class MappedListXmlAdapter extends XmlAdapter<JaxbHashMapList, MappedList> {
{code}

Same apply for more complex XmlAdapter. Following throws exception.
{code}
public class EnumWrapperAdapter<T extends Enum<T>> extends XmlAdapter<T, EnumWrapper<T>>
{
{code}
After this update it is ok
{code}
public class EnumWrapperAdapter extends XmlAdapter<Enum, EnumWrapper> {
{code}

*This is regression as it works with plugin version 2.5.2*
