Random nullpointer exception

[fredwilliamson]

Hi,
We used your API in version 2.1.0 to upload a document in S3 without having the size of the file. It worked on 95% of upload but for some of them we have the following error:

java.lang.NullPointerException: null
at alex.mojaki.s3upload.StreamTransferManager.complete(StreamTransferManager.java:322)
at XXXXX.S3Adapter.createDocument(S3Adapter.java:103)

We don't find any relation between cases where it failed or not. This is the implemantation we did with your API

public Document createDocument(Document document , InputStream stream) throws DocumentManagementException {
    StreamTransferManager manager = new StreamTransferManager(this.bucketname, getKey(document.getDocumentRef()), this.s3client){
        @Override
        public void customiseInitiateRequest(InitiateMultipartUploadRequest request) {
            super.customiseInitiateRequest(request);
            ObjectMetadata metadata = new ObjectMetadata();
            metadata.addUserMetadata("d_doc_extension" , "." + FilenameUtils.getExtension(document.getDocumentName()));
            metadata.addUserMetadata("d_doc_name" , document.getDocumentRef());
            request.setObjectMetadata(metadata);
        }
    }.partSize(30);



    try (MultiPartOutputStream os = manager.getMultiPartOutputStreams().get(0)) {
        IOUtils.copy(stream, os);
        stream.close();
    } catch (IOException e) {
        e.printStackTrace();
        throw new DocumentManagementException(e.getMessage());
    } finally {
        manager.complete();
    }



    ObjectMetadata meta =  this.getDocumentMetadata(document.getDocumentRef());
    document.setFileSize(meta.getContentLength());
    return document;
}

Can you help us to find the issue ?

Regards

Hi, sorry this slipped my mind, but have you tried upgrading to the latest version 2.2.1?

Closing until this gets confirmed again.
