Cheng Fang commented on WFLY-10173:
-----------------------------------

Changed title to remove 'windows' as this test may failed on other platforms too. The latest PR was updated on 2020-06-05 to fix this issue.

> Sometime, when running EjbInvocationStatisticsTestCase on Windows, assertion fails, as wait-time is 0 (verified it is 0 by adding debug message).
> For me it fails allTests in most of cases, but when running test standalone, it fails only in 1 of 4 cases.
> I suppose it is because of too short sleep in AbstractManagedBean. (in test is called 4 times, each invocation include 50ms sleep, so I consider probable the wait-time is 0 - need to use longer sleeps to fulfill the test)
