   ```suggestion
           for (int i = 0; i < numRemoteHandles; ++i) {
               for (int j = 0; j < numSubHandles; ++j) {
                   contents[i][j] = new byte[random.nextInt(100000) + 1];
                   random.nextBytes(contents[i][j]);
               }
           }
   ```
   Necessary change to pass checkstyle.
