FU Ant task failure: java.util.concurrent.ExecutionException: could not close client/server socket

Mar 24, 2011 8:30 AM

We sometimes see this failure intermitently when using the FlexUnit Ant task to run tests in a CI environment. The Ant task throws this exception:

 

java.util.concurrent.ExecutionException: could not close client/server socket

 

I have seen this for a while now, and still see it with the latest 4.1 RC versions.

Here is the console output seen along with the above exception:

 

FlexUnit player target: flash

When the problem occurs, it is not always during the running of any particular test (that I am aware of). Recent runs where this failure was seen had the following number of tests executed (note: the total number that should be run is 45677): 18021, 18, 229.

 

Here is a "good" run when the problem does not occur:

Has anyone else ran across this problem?

 

Thanks,

Trevor

    No one else has encountered this?  My platform is Windows, by the way. Thanks for any help anyone can offer...

    Hey Trevor,

     

    The only windows server I work with is our actual FlexUnit build server.  It is not currently using the AIR runner just the flash runner.

     

    When this kind of stuff happens I find its usually because the AIRCIListener is not being used.  That is the tool that actually closes app.  You would use that instead of the normal CI listener in your runner.

     

    Confirm you have that working and if that is not it, I'll setup a task on the flexunit build server to run the air runner from ant and see if it is able to finish.

     

    Thanks,

    Simeon,

     

    Thanks for responding.

     

    These particular tests are Flex based only - they do not use AIR. Therefore, I am using the regular Flex "CIListener" class.  Are you saying that even though the tests are Flex, one should still use the AIRCIListener?

     

    Thanks,

    Trevor

    No sorry,  I thought the problem was related to AIR.

     

    The Listener you use is based on the the runtime environment, not the framework.  So if you are running the tests in Flash Player, then the CI listener is good enough.

     

    Consequently we are using this in our build system.  In fact we build everything from the ground up each time, so we create the ant tasks and the listeners so that we can test the framework.  And all our tests are passing which means the flash player was able to be closed.

     

    Let me ask around and see if anyone else has seen anything odd.

    Well, after running the tests locally on my own machine, I discovered that the Flash Player is crashing during the test execution. I have never seen this before.  I suppose it is time to ask the developer to attach the debugger and step through the tests?  Is there perhaps any generic guidance I should provide to the owner of these tests?

    Wow. Haven't seen that one before.

     

    No, can't provide any guidance but it would be good to find out the cause and be sure we notify Adobe as well.

    Not sure if my flash player is crashing or not but I've been seeing that same error running a CI flexunit task from ant. In my case I'm running

    Ubuntu 10.10 (64 bit). If I come up with anymore details I'll post them here.

    I am not sure if this information will help everyone, but here goes...

     

    For us, these problems with FlexUnit tests crashing the Flash Player appear to be related to couple of factors. Recently, we moved up from Flex 3.2 to Flex 4.1 as our development baseline.  Many people complained that their development environment (Flash Builder, etc.) was much more unstable.  Apparently, 4.1 produces SWFs that require more memory to run than 3.2 does?  Anyway, we still had Flash Player 10.1 as our runtime baseline.  Apparently, that version of the player was not as capable of running larger FlexUnit test SWFs, and would crash (as I posted months earlier).  I upgraded to the latest 10.3 standalone player versions, and the crashes have now ceased.  It would be nice to know exactly what was causing the crashes, but memory management (or lack of) is my best guess.

     

    So, if you are seeing these issues, try upgrading to the latest Flash Player version.

     

    Regards,

    Trevor
