mDataHandler failed to consume data

[xmuSistone]

Hello,

i got this error:
java.lang.RuntimeException: mDataHandler failed to consume data, yet remains the mDataHandler.
at com.koushikdutta.async.Util.emitAllData(Util.java:39)
at com.koushikdutta.async.AsyncNetworkSocket.onReadable(AsyncNetworkSocket.java:160)
at com.koushikdutta.async.AsyncServer.runLoop(AsyncServer.java:878)
at com.koushikdutta.async.AsyncServer.run(AsyncServer.java:726)
at com.koushikdutta.async.AsyncServer.access$800(AsyncServer.java:46)
at com.koushikdutta.async.AsyncServer$8.run(AsyncServer.java:680)

in my case, i called setMultipartCallback :
MultipartFormDataBody body = (MultipartFormDataBody) request.getBody();
body.setMultipartCallback(part -> {
DataHolder dataHolder = new DataHolder(part.getName());
body.setDataCallback(dataHolder);
});

after data arrived and completed, i called this:
response.send("application/json; charset=utf-8", result); //AsyncHttpServerResponse

can you please figure out what my mistake is?

Not everytime, but it's happening to me as well sometimes and it's crashing the application...
