WWDuplicateRequestException

[peterdn1]

We frequently run WWJ from within eclipse. When the application is started WWDuplicateRequestException is thrown a number of times. Would it be possible to not to submit the duplicate request, or alternatively not throw the exception and return from the method.
Daemon Thread [Thread-17]
(Suspended (exception WWDuplicateRequestException))
ThreadPoolExecutor$Worker.run() line: not available
Thread.run() line: not available protected void beforeExecute(Thread thread, Runnable runnable)
...
if (ThreadedTaskService.this.activeTasks.co ntains(runnable))
{
String message = Logging.getMessage("ThreadedTaskService.CancellingDuplicateT ask", runnable);
Logging.logger().finer(message);
return;//NEW CODE
//OLD CODE: throw new WWDuplicateRequestException(message);
}
...

There are several threads on duplicate requests, number of tries, time to next try, etc.
This is handled extremely well compared to how it was before.

The time required for a duplicate request is very small.

For things like this I just figure out to prevent the printing of the error.

[peterdn1]

If this is expected behavior which I have no issue with, then I would recommend not thowing the exception and just returning from the method when a duplicate request is sent.

[nlneilson]

For some reason they want the error printed.
What they have for reporting is FINE, FINER, ... but no OFF.
I don't know how that is used.

One thing was when offline there was a lot of printing.
I did not want to change a key or variable for that or expect a user to do it.
I have an app that can be run from a .bat or .bash file and what is printed can
be used to track down problems from a user or myself.
I don't want a lot of printing of messages that are not necessary.

To get rid of those re offline:
util/SessionCacheRetrievalPostProcessor.java
line #202 and #205 comment
add return null; to line #206

You are not having a problem of your app running are you?

I am not having an issue running the application and the issue with debugging is a minor annoyance. It appears that duplicate requests are handled correctly(the second request discarded) and cause no issues. This seems like a reasonable approach,why throw the exception. Creating a stack trace is not free and throwing the exception adds no value?

Creating a stack trace is not free and throwing the exception adds no value?

I agree!

As of the 2/27/2011 release the exception is no longer thrown. The log message is still generated, however, but only at log level FINER.

Thank you.

The latest available from http://builds.worldwind.arc.nasa.gov/download.asp
is 2/26/2011.

When will a version be available that includes the exception/logging changes?

edit: In the last 2 weeks the SDK has gone from ~38 to ~50MB, will be interesting
to see what has been added.
Not many projects are updated, bug fixes, additions, etc. as much as WWJ.

Great project!

The daily builds have been restored. Sorry about the outage. I triggered a manual build so today's snapshot is there right now.

We made a change to Javadocs and it caused the build server to crash.

[nlneilson]

Great. I will be heading out tonight for a ~week and am glad to have the latest to take with me.

Thanks Randy
