Thanks.

Sorry, there appears to be a problem with using this in practice. Apparently the body is getting loaded implicitly somewhere, and the second invocation (with stream) is throwing an exception. I'm trying to track it down at which point I'll update the tests and PR

Please create a PR if you fix it :-). Maybe I'll find some time to debug it soon.

It all comes down to Net::HTTP insisting on reading the body when a request is made. In particular request /does/ allow a block during which the body has not been read. But after the block is invoked, it reads whatever content in the body hasn't been consumed by the block.

I have a fix working, but it makes things a fair amount uglier. Perhaps there's a better adapter to use?

I'm mostly interested this because I'm constrained to using JRuby, and have found other libraries for S3 access to either not play nicely with JRuby or to make some odd assumptions. I'll push a new branch once I've got tests passing, though they need a bit of rejiggering.
