Re : Liquibase Update command not executing rollback changesets

By specifying an empty rollback tag, you have effectively told Liquibase "this does not need to be rolled back". Since the createTable change can automatically be rolled back, just removing the rollback tag should accomplish what you want. If you wanted to do more than just drop the table on rollback, you could add more to the rollback tag.
