-------------------------------- The Reason
-------------------------------------------
JaxWsServiceConfiguation.java line 242:
private String getDefaultLocalName(OperationInfo op, Method method, int
paramNumber,
int curSize, String prefix) {
String paramName = null;
if (paramNumber != -1) {
paramName = prefix + curSize;
} else {
paramName = prefix;
}
return paramName;
}
should be changed from "paramName = prefix + curSize;" to
"paramName = prefix + paramNumber;"?
