ADDITIONAL OS VERSION INFORMATION :
Windows 7 enterprise
A DESCRIPTION OF THE PROBLEM :
I'm using the ZipFile Class to get the ZipEntry of a zipfile . And depending on their name I stream the entries to a database.
This works using : ZipFile zipFile = new ZipFile(file);
But only when the zipfile extracted size is below 4 GB . When bigger this gives a ZipException: invalid CEN header (bad signature).
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
ZipFile zipFile = new ZipFile(file);
final Enumeration<? extends ZipEntry> entries = zipFile.entries();
while (entries.hasMoreElements()) {
ZipEntry nextElement = entries.nextElement();
System.out.println("nextElement " + nextElement.getName());
}
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A print of the entries.
ACTUAL -
A print of the entries when the extracted size is below 4 GB, an error otherwise.
