[GitHub] [pulsar] lhotari commented on issue #19297: Flaky-test: ReplicatorTest.testDoNotReplicateSystemTopic

URL: https://github.com/apache/pulsar/issues/19297#issuecomment-1398082751

   There's also #12774, but the problem seems to be different.
   
   In this case, it looks like there's a race condition in the test itself.

   @nicoloboschi can you check this since you added `consumerFromR2` in #18896?
   
   It seems that the problem is that `consumerFromR2` will auto-create the topic in r2 and there's a possibility that r2 creates the topic in r1 when replication starts? That's why the line 1499 could fail with ConflictException?
