The internal exception which is wrapped in java.sql.SQLNonTransientConnectionException is of Type :- software.aws.rds.jdbc.mysql.shading.com.mysql.cj.exceptions.CJException.
This exception extends RuntimeException and not SQLException, therefore, the internal exception will be skipped and secrets won't get rotated.

The custom codefix which I tested :-
private boolean isLoginUnsuccessful(SQLException exception) { this.logger.logTrace("Login failed. SQLState=" + exception.getSQLState(), exception); Throwable t = exception; do { if (t instanceof SQLException) { if (((SQLException) t).getSQLState().equals(SQLSTATE_ACCESS_ERROR)) { return true; } } if (t instanceof CJException) { if (((CJException) t).getSQLState().equals(SQLSTATE_ACCESS_ERROR)) { return true; } } t = t.getCause(); } while (t != null); return false; }
