When we are migrate to 2.4.1 from 2.3.1 we have an exception with wadl generation

Investigation shown that exception cause for next method:
@POST
@Path("/
/replyInfo")
@Consumes(
)
public ResourceIdentity processReplyRequestedInfo( @PathParam("id") final Integer id, @FormParam("comments") final String comments)
when change method signature to:
public ResourceIdentity processReplyRequestedInfo( @FormParam("comments") final String comments, @PathParam("id") final Integer id )
resolves issue.
Analysis of source code for class org.apache.cxf.jaxrs.model.wadl.WadlGenerator.java provide conclusion why it happen.
Chain of calls:
private boolean handleOperation(StringBuilder sb, Set<Class<?>> jaxbTypes,
ElementQNameResolver qnameResolver,
Map<Class<?>, QName> clsMap,
OperationResourceInfo ori,
OperationResourceInfo nextOp,
boolean resourceTagOpened,
int index) {
....
if (isFormRequest(ori)) {
358: handleFormRepresentation(sb, jaxbTypes, qnameResolver, clsMap, ori, getFormClass(ori));
859: private Class<?> getFormClass(OperationResourceInfo ori) {
if (ori.getParameters().get(0).getType() == ParameterType.FORM)
else
{ return MultivaluedMap.class; }}
in case of first parameter is @PathParam the formClass returned value MultivaluedMap.class and exception thrown.
in
private void handleFormRepresentation(StringBuilder sb, Set<Class<?>> jaxbTypes,
ElementQNameResolver qnameResolver,
Map<Class<?>, QName> clsMap, OperationResourceInfo ori,
Class<?> type) {
617: if (type != null) {
handleRepresentation(sb, jaxbTypes, qnameResolver, clsMap, ori, type, true);
.....
if (inbound) {
573: int index = getRequestBodyParam(ori).getIndex();
599:private Parameter getRequestBodyParam(OperationResourceInfo ori) {
for (Parameter p : ori.getParameters()) {
if (p.getType() == ParameterType.REQUEST_BODY)
}
throw new IllegalStateException();
