Reproduce the failure by running cloudcv.run() and start with the stack trace in UploadData.java, especially getToken at line 229 and CloudCVPostRequest at line 290. Inspect the Apache HTTP client classes involved in DefaultHttpClient.createHttpParams and identify the compatibility problem; done means the VerifyError no longer occurs and the request completes successfully.
