In case when dht::boot_strapper::get_boostrap_tokens fail to parse the tokens, the topology coordinator handles the exception and schedules a rollback. However, the current code tries to continue with the topology coordinator logic even if an exception occurs, leaving boostrap_tokens empty. This does not make sense and can actually cause issues, specifically in prepare_and_broadcast_cdc_generation_data which implicitly expect that the bootstrap_tokens of the first node in the cluster will not be empty. Fix this by adding the missing break. Fixes: scylladb/scylladb#23897 From the code inspection alone it looks like 2025.1 and 6.2 have this problem, so marking for backport to both of them. Closes scylladb/scylladb#23914 * https://github.com/scylladb/scylladb: test: cluster: add test_bad_initial_token topology coordinator: do not proceed further on invalid boostrap tokens cdc: add sanity check for generating an empty generation

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
