Alex Rudyy updated QPID-3794:
-----------------------------
Attachment: 0001-QPID-3794-fixes-ocasional-test-StatisticsCounterTest.patch
Attached a patch with a potential problem fix.
I could not reproduce the issue locally.
I believe that the only reason why this test failed is that the sequential invocations of Thread.sleep() caused current thread to sleep for more time than it was expected.
Thread.sleep(1500);
Thread.sleep(1000);
The total expected sleeping interval is 2500 mls.
It seems that for failed test the thread slept for more than 3000+ mls in total during first 2 sleep invocations and as result of it the counter peak value was evaluated due to finishing the sample period which is 1 second.
It seems that thread overslept for more than 500mls which is quite unexpected value. Perhaps, extra GC activity caused it. I am not sure.

Robbie Gemmell commented on QPID-3794:
--------------------------------------
I have applied the patch, with a small update to ensure it doesnt result in negative values being used which will simply lead to a new failure mode. The patch looks like it should help, but it clearly wont be able to entirely fix the underlying issue leading to these sporadic failures; the tests highlights that they are pretty ugly and slightly indeterminate given their complete reliance on Thread.sleep() functionlity, so I have raised QPID-3811 to track future effort to make them more determinate (and faster!).
