Please read https://stackoverflow.com/help/minimal-reproducible-example
**Describe the issue**
I'm trying to use a three-dimensional array. However, I found that I can retrieve the result set normally in regular mode, but an error occurs **in binary mode**.
**Driver Version?**
42.7.7
**Java Version?**
java 21
**OS Version?**
Windows 10
**PostgreSQL Version?**
PostgreSQL 14.18
**To Reproduce**
Steps to reproduce the behaviour:
```
import java.sql.*;
import java.util.Properties;
public class TestMultiDimensionalArrayRetrieveResultSets {
public static void main(String []args) throws Exception {
String url = "jdbc:postgresql://localhost:5432/test";
Properties props = new Properties();
props.setProperty("user", "test");
props.setProperty("password", "test");
// forceBinary
props.setProperty("prepareThreshold", "-1");
Connection conn = DriverManager.getConnection(url, props);
Statement stmt = conn.createStatement();
stmt.execute("DROP TABLE IF EXISTS TestArray");
stmt.execute("CREATE TABLE TestArray(intarr int[])");
stmt.execute("INSERT INTO TestArray VALUES ('{{{0},{1}},{{2},{3}},{{4},{5}}}')");
ResultSet rs = stmt.executeQuery("SELECT intarr FROM TestArray");
rs.next();
// {{{0},{1}},{{2},{3}},{{4},{5}}}
Array arr = rs.getArray(1);
ResultSet arrrs = arr.getResultSet();
arrrs.next();
// {{0},{1}}
Array arr1 = arrrs.getArray(2);
ResultSet arr1rs = arr1.getResultSet();
arr1rs.next();
// {0}
Array arr11 = arr1rs.getArray(2);
ResultSet arr11rs = arr11.getResultSet();
arr11rs.next();
System.out.println(arr11rs.getInt(2));
arr11rs.next();
arr11rs.close();
arr1rs.next();
// {1}
Array arr12 = arr1rs.getArray(2);
ResultSet arr12rs = arr12.getResultSet();
arr12rs.next();
System.out.println(arr12rs.getInt(2));
arr12rs.next();
arr12rs.close();
arr1rs.next();
arr1rs.close();
}
}
```
**Expected behaviour**
I expected to be able to retrieve the values in a three-dimensional array, but it actually got an error **in binary mode**:
```
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: arraycopy: last source index 33554459 out of bounds for byte[84]

```

Hi @davecramer @vlsi
I've found the bug and fixed it in #3746
Please review the code, thx :-)
