Research direction

Start at DbxDownloader.close() in DbxDownloader.java:131 and reproduce the cancelDownload sequence from the report. Trace the IOUtil.closeQuietly and Android OkHttp source-close frames to determine why cancellation causes “Unbalanced enter/exit.” Done means closing an active downloader no longer throws this exception, with coverage for the cancellation sequence.

              dbxDownloader = null;
          }
    }

When I call dbxDownloader.close(); is thworing an exception. The exception is this
