Description

        if (columns != null) {
            StringUtil.toUpperCaseArray(columns, columns);
        }

        if (model != null) {
            table = model.findTable(table).getAlias();
            for (int i = 0; i < columns.length; i++) {

In the second if block, columns is accessed without null check.
