Issue

• We have the following code

private byte[] zipFiles(ArrayList<byte[]> files) throws IOException {
        log.info(files.size());
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ZipOutputStream zos = new ZipOutputStream(baos);
        int i = 0;

        for (byte[] pdf : files) {
            ZipEntry entry = new ZipEntry("doc_" + i++ + ".pdf");
            entry.setSize(pdf.length);
            log.info("Pdf len: " + pdf.length);
            zos.putNextEntry(entry);
            zos.write(pdf);
            zos.closeEntry();
        }
        baos.flush();
        zos.close();
        baos.close();
        return baos.toByteArray();

    }

• In a processor, we do

byte[] out = zipFiles("Araaylist files "); 
exch.getIn().setBody(out, byte[].class);

• When we write this output directly to the file system the zip file is correct !
  e.g. to(file:/path/to/file) OK . Zip is ok

• When we return this body as cxfrs response , we get a corrupt file. This used to work correctly in version 6.0 / with cxrfs .
  Also when we try to email this zip file / it comes out corrupt. Email go through an email queue .camel smtp .
