Defect in IBM Java SDK affects MultithreadedTC (Thread.getState()) about multithreadedtc

[GoogleCodeExporter]

This looks like it might be difficult to solve. But I will download the IBM JDK 
and
investigate what states the treads are in.

Is there any chance that this will be fixed? As we are now running more tests 
in IBM JVMs, we will otherwise have to work around this.

Thank you!

Sorry for the delay. I have not been able to download the IBM JDK or find a 
workaround. Any ideas?

I will have a little more time to look at this once I complete my dissertation 
in August.

Thanks,
Nat

Hello Nat, thank you for your quick reply. For us it would be best to switch 
back to the old behaviour, at least for Java 1.5. I think there won't be any 
perfect fix for this.
Thanks
Marcel

Hi Marcel, 

We have only had two releases, so feel free to download the original version 
(1.0) to see if this works for you (just search for deprecated downloads). I 
don't think there is any other applicable version. Otherwise you may need to 
use a workaround.

I will take a closer look at this in mid-August, once I graduate.

Cheers,
Nat

Hi Nat,
sorry for the late reply. I hope your graduation was successful. I tried 
version 1.0 (I compliled it myself as it was compiled for Java 6) and the 
problem was already there. In fact, the workaround was introduced in 1.01, 
because if you are running the JDK-1.4-Code (// JVM does not support 
Thread.State), it works.
It is annoying, because it's not MTC's fault, but a defect in IBM's JDK. The 
only problem in MTC is maybe that it's not using the Thread API as documented 
(getState(): "This method is designed for use in monitoring of the system 
state, not for synchronization control."
Thanks and best regards
Marcel
