This is nothing to worry about. jclouds creates temporary files when HTTP payloads exceed 256 KB to avoid exhausting memory. You can see the source of this message at core/src/main/java/org/jclouds/logging/internal/Wire.copy. I believe that this code is only exercised with debug logging; usually jclouds streams payloads directly.
