When wrong column name is used to retrieve the column value from a table, an SQLException is thrown but the exception contains vendor code 0 and SQL state null though error message is as expected.

You can reproduce the problem using attached JDBC program.
Here is the sample output:
Connected to jdbc:mariadb: ....<removed actual info purposefully>
