Andres de la Peña commented on CASSANDRA-18360:
-----------------------------------------------
The test failure can be reproduced by running the test method separately,
without running the entire test class:
{code}
.circleci/generate.sh -p \
-e REPEATED_UTESTS_COUNT=500 \
-e
REPEATED_UTESTS=org.apache.cassandra.cql3.validation.operations.AlterTest#testDropListAndAddListWithSameName
{code}
[Bisection|https://app.circleci.com/pipelines/github/adelapena/cassandra?branch=18360-trunk-bisect]
shows that the commit where the test started to fail for the first time is
[0bed1967fdd1caeb2bbc38645c2a0cb7e728725c|https://github.com/apache/cassandra/commit/0bed1967fdd1caeb2bbc38645c2a0cb7e728725c].
That commit belongs to CASSANDRA-18125, which seems the ticket where the test
failure was introduced.
[This

for the commit immediately before CASSANDRA-18125 succeeds.
[This other
run|https://app.circleci.com/pipelines/github/adelapena/cassandra/2757/workflows/ebbe5032-fc89-41c1-9603-f4336f20cdc3]
for the 4.1-trunk merge commit of CASSANDRA-18125 fails reproducing the
current issue.
[This
run|https://app.circleci.com/pipelines/github/adelapena/cassandra/2745/workflows/6eb7b890-40de-4ffe-b1f7-16b26ed19b42]
for the current 4.1 branch successes, suggesting that the failure only affects
trunk. I haven't tested 4.0 yet.
