IW3 missing when downloading product from Data Space

Microwave Toolbox
6

FYI, I reported the problem to the Copernicus Data Space Ecosystem on 30/08/2023.
I did some further investigation and provided came up with a minimal code snippet to reproduce the error in Java 1.8.

package org.example;

import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipException;
import java.util.zip.ZipFile;

public class Main {
    public static void main(String[] args) {
        String zipPath = "/home/stijn/Downloads/S1A_IW_SLC__1SDV_20230829T054319_20230829T054347_050086_0606E8_2748.CDSE.zip";

        try (ZipFile zipFile = new ZipFile(zipPath)) {
            Enumeration<? extends ZipEntry> entries = zipFile.entries();
            while (entries.hasMoreElements()) {
                ZipEntry entry = entries.nextElement();
                System.out.println(entry.getName());
                if (!entry.isDirectory()) {
                    try (InputStream inputStream = zipFile.getInputStream(entry)) {
                        inputStream.read();
                    } catch (ZipException e) {
                        System.err.println("Failed to read " + entry.getName());
                    }
                }
            }
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

Output:

I provided my findings on 06/09/2023, but the problem remains unsolved.

Since it is a compatibility issue with the built-in ZIP reader in Java 1.8, I’m afraid this cannot be solved easily on the side of SNAP either.
