When any liquibase exception is thrown and it catches in LiquibaseJpaUpdaterProvider update method inside try\catch block, an exception will be retrown like RuntimeException, but it will not be logged anywhere. It reaches platform.exit(t) and then only message of wrapped RuntimeException is propagated. But real caused can be noticed only via debug mode.
