Zack Shoylev commented on JCLOUDS-1064:
---------------------------------------
Hm, no, the null pointer exception happens when the regular (one single part)
PUT upload returns a null etag somehow (even though the log has an Etag in the
response). Using the log you provided, I have not been able to reproduce this.
Another question for your code: it should be sufficient to supply just the
file, you shouldn't have to supply md5 or length. The example we use usually
just has something like:
Blob blob =
blobStore.blobBuilder(objectName).payload(Files.asByteSource(input))
.contentType(MediaType.APPLICATION_OCTET_STREAM).contentDisposition(objectName).build();
(from here:
https://github.com/jclouds/jclouds-examples/blob/master/blobstore-largeblob/src/main/java/org/jclouds/examples/blobstore/largeblob/MainApp.java)
I will try a few more things, but can you modify your code to be closer to the
example code and see if this still happens?
