I have a CachedRowSet object in Java. Since CachedRowSets are disconnected from the DB, is there a need to close them, or put them in try-with-resources blocks? My IDE is suggesting I should.

Here is how I am using it, I fill the CachedRowSet from a query (and use try-with-resources for the PreparedStatement and ResultSet objects)

public static void resultSetParsing(Connection con) throws Exception {
        String sqlStatement = " select id, name from TestTable ";

        CachedRowSet cachedRowSet = null;

        try(PreparedStatement pstmt = con.prepareStatement(sqlStatement)){
            try(ResultSet rs = pstmt.executeQuery()){

                cachedRowSet = RowSetProvider.newFactory().createCachedRowSet();

                // Fill the CachedRowSet from the ResultSet
                cachedRowSet.populate(rs);
            }
        }

        // I am disconnected from the DB at this point
        while(cachedRowSet.next()){
            System.out.println("Found item: " + cachedRowSet.getString("id") + " " + cachedRowSet.getString("name"));
        }
    }

Does it matter that I am not closing it at the end? I want to use this object properly.
