Here's another way of doing it using Files.copy().

    private long downloadReport(String url){

            long bytesCopied = 0;
            Path out = Paths.get(this.fileInfo.getLocalPath());

            try {

                 WebTarget webTarget = restClient.getClient().target(url);
                 Invocation.Builder invocationBuilder = webTarget.request(MediaType.TEXT_PLAIN_TYPE);

                 Response response = invocationBuilder.get();

                 if (response.getStatus() != 200) {
                    System.out.println("HTTP status " response.getStatus());
                    return bytesCopied;
                 }

                 InputStream in = response.readEntity( InputStream.class );
                 bytesCopied = Files.copy(in, out, REPLACE_EXISTING);

                 in.close();

            } catch( IOException e ){
                 System.out.println(e.getMessage());
            }

            return bytesCopied;
     }
