Pritesh updated COMPRESS-538:
-----------------------------
Description:
When creating a zip file using
[ZipArchiveOutputStream(File)|https://commons.apache.org/proper/commons-compress/apidocs/org/apache/commons/compress/archivers/zip/ZipArchiveOutputStream.html#ZipArchiveOutputStream-java.io.File-]
constructor each entry get an extra `Zip64ExtendedInformationExtraField`
header which shouldn't be there.
The issue can be reproduced using below code sample
{code:java}
public static void main(String[] args) throws IOException {
// Create file
final File file = File.createTempFile("apache_", ".zip");
try ( ZipArchiveOutputStream zos = new ZipArchiveOutputStream(file)) {
zos.putArchiveEntry(new ZipArchiveEntry("TextFile1.txt"));
zos.closeArchiveEntry();
}
// List Headers File
final ZipFile zipFile = new ZipFile(file);
final Enumeration<? extends ZipArchiveEntry> entries =
zipFile.getEntries();
while (entries.hasMoreElements()) {
final ZipArchiveEntry entry = entries.nextElement();
for (ZipExtraField zipExtraField : entry.getExtraFields()) {
System.out.println("EntryName:" + entry.getName() + " Header:
"+ zipExtraField.getHeaderId().getValue()); // Header shouldn't be present.
}
}
}
{code}
