Description with failing test case

Hey folks, hope you can help me :)

When I try to retrieve a buckets policy I get "java.lang.Character cannot be cast to java.util.Map$Entry"

(def s3 (aws/client {:api    :s3
                               :region "us-east-1"
                               :endpoint-override {:hostname "s3.example.com"}
                               :credentials-provider (aws-credentials/basic-credentials-provider
                                               {:access-key-id     "access-key"
                                                :secret-access-key "secret-key"})}))
(def res (aws/invoke s3 {:op :GetBucketPolicy
                            :request {:Bucket "bucket-name"}}))

Thanks for the bug report @BenJanecke. Fix is on master, release coming shortly. I'm surprised this never came up before as this has been broken since our very first release. One reason might be that of 7823 operations across 227 services, GetBucketPolicy is the only operation with the particular output structure that triggered the bug!

Fix released in version "0.8.474".
