Bret McGuire commented on CASSJAVA-138:
---------------------------------------
Hmmm, this might not be related to Java17 at all. I noted something similar
while running a test build for CASSJAVA-115... but in that case the only
failures were for Java11:
{noformat}

Might just have an outright flaky test

> A couple things are of interest here:
> * The tests only fail on Java17. The Jenkins build runs tests for Java8,
> Java11, Java17 and Java21 but only Java17 seems to fail
> * I do not see any equivalent failure on test runs of the 4.x branch
> ** In fairness the 4.x branch would still have the geometry issue referenced
> in CASSJAVA-136 but as mentioned above there's no correlation between that
> issue and this test
> * The [test provider in
> question|https://github.com/apache/cassandra-java-driver/blob/e15da70e9fe2856bbcb27ab141b755440ca39ca9/integration-tests/src/test/java/com/datastax/dse/driver/api/core/cql/continuous/ContinuousPagingITBase.java#L84-L108]
> has 10 distinct options and no test is failing for all 10 options
> * Tests for a given version of DSE are not consistent between runs
> All this evidence together seems to argue for a flaky integration test... but
> I don't see anything obviously wrong with it
