Milan,
I'm observing the latest version (.04) of this test failing quite frequently
(4/100) on Windows (Windows Server 2012 R2 6.3 (amd64)) machines. The test
passes fine on macOS and Linux. Here's the typical output I see in the logs:
java.lang.RuntimeException: Query took 4997 ms. . Timeout value is 5000
java.lang.RuntimeException: Query took 4999 ms. . Timeout value is 5000
java.lang.RuntimeException: Query took 4995 ms. . Timeout value is 5000
java.lang.RuntimeException: Query took 4998 ms. . Timeout value is 5000
...
Now, there might be many reasons for that. One of which would be that the
DnsClient code is buggy. The other reason would be that the accuracy guaranteed
by Windows implementation of `read` is not what we would expect. Would you be
able to investigate that?
P.S. The good news is that the CSR has been approved:
