Dilip Simha commented on JCLOUDS-1251:
--------------------------------------
An NPE doesn't sound good. I happened to see this bug too and after digging
deeper discovered that Openstack-Swift sent a 404 error since it could not find
the requested object. Surprised that Jclouds throws an NPE instead of relaying
the 404 error for the removeBlob case.
More importantly, the API for removeBlob is insufficient as it cannot handle
the case where the blob is not present.
I would opt to see either an exception or return a success/failure value to
confirm if blob was not removed or not.
Any comments ?
