             Summary:  Error while getting schema in  mysql
                 Key: METAMODEL-1100
                 URL: https://issues.apache.org/jira/browse/METAMODEL-1100
             Project: Apache MetaModel
          Issue Type: Bug
            Reporter: Arun Pillai


 I'm trying to list all table names from a schema
 I'm getting the following error

         String connectionURL =  "jdbc:mysql://localhost:3306";
         String userName = "user";
         String password = "pass";

          DataContext dataContext =
 DataContextFactory.createJdbcDataContext(connection);
          Schema schemas = dataContext.getSchemaByName("exampledb");
Please find the error stack
