After switching the database driver from mysql-connector-java to mariadb-java-client in one of our applications, stored procedures called with SimpleJdbcCall no longer worked and failed with an exception like java.sql.SQLSyntaxErrorException: Incorrect number of arguments for PROCEDURE foo.bar; expected 12, got 0.

After some investigation I noticed that the CallMetaDataProviderFactory has a list called supportedDatabaseProductsForProcedures (which contains MySQL, but not MariaDB) so accessProcedureColumnMetaData was set to false and initializeWithProcedureColumnMetaData was not called on the CallMetaDataProvider; thus no parameters where added to the procedure call, resulting in the SQLSyntaxErrorException.

So I think MariaDB should be added to the supportedDatabaseProductsForProcedures.
