Re: ResultSetMetaData getColumnClassName accuracy for JDBC

I'm not sure that your use case is aligned with JDBC understanding of what this method should return. There is a test case that checks, among other things that

resutSet.getObject(index).getClass().getName() is the same as resultSetMetaData.getColumnClassName(index)

See here https://github.com/MariaDB/mariadb-connector-j/blob/master/src/test/java/org/mariadb/jdbc/DatatypeTest.java

That in my understanding, was what JDBC required. Why would you need to instantiate Objects with newInstance at all, what are you trying to achieve

I'm testing one of my theories. I'll just make adaptation similar to the getClassName [1] and use getColumnType as that seems to be more reliable and the returned type seems to be one of the java.sql.Types.

Thanks, Tommy
