I'm trying to use lingala zip4j to archive X509Certificate files.
However, I am getting this strange exception only when I am unit testing with Junit.
If I run my application as a product (which is a spring web app) - it works fine with no exceptions and I am able to properly archive and un-archive files with no issues.

Here is my Utils code which archives the certificates that I have used:

throws IOException, CertificateEncodingException, ZipException {

// Create ZIP file
for (X509Certificate certificate : certificateList) {
if (certificate == null) {

continue;
}
File file = File.createTempFile(UUID.randomUUID().toString(), ".cer");
file.deleteOnExit();
outputZipStream.putNextEntry(file, zipParameters);
outputZipStream.write(CertificateTestUtils.encodeCertificate(certificate));
outputZipStream.closeEntry();
}
//finish up
outputZipStream.finish();
bytes = outputStream.toByteArray();
return bytes;
}

// Create ZipParameters

// Set how you want to encrypt files

return zipParameters;
}
}
I'm using Java 1.6
I've also tried using 1.8 but I am getting the same error.
Note: This is only happening when I run with Junit...
