Two methods:
public void updateSubscriber(SubscriberRequest request) {
long time = System.currentTimeMillis();
try {
Thread.sleep(20000);
} catch (Exception e) {
}
log.warn("UPDATE " + request.getClientId() + " : " +
String.valueOf(time));
}
public void disableSubscriber(SubscriberRequest request) {
long time = System.currentTimeMillis();
try {
Thread.sleep(20000);
} catch (Exception e) {
}
log.warn("DISABLE " + request.getClientId() + " : " +
String.valueOf(time));
}
The client looks like this:
OurServiceSOAP11PortStub portal =
new OurServiceSOAP11PortStub (url);
ServiceClient serviceClient = portal._getServiceClient();
Options options = serviceClient.getOptions();
options.setProperty(HTTPConstants.CHUNKED, new Boolean(false));
client.setPortal(portal);
Scenario:
We have 2 instances of the client, client1 and client2.
1- Client1 calls updateSubscriber
2- A couple of seconds later, client2 calls disableSubscriber
3- Client2 obtains a valid response, and the following log line is printed
WARN
[http-8080-1][][com.qualcomm.bcs.recommendation.RecommendationServiceImpl]
DISABLE client2 : 1195034820156
4- Client1, after printing the following log line...
WARN
[http-8080-2][][com.qualcomm.bcs.recommendation.RecommendationServiceImpl]
DISABLE client1 : 1195034819759
(Which is printed BEFORE the client2's one. Note the log.warn() call is the
same, but the request and the millis are not)
... throws this exception

Highlighted in bold the mismatch between what was supposed to be an
updateResponse and got a disableResponse instead.
