[Java SDK V2] How to do batch upload?

For some reason my posts are disappearing from this thread.

I closed the session like this:

tested.files().uploadSessionAppendV2(cursor, true).uploadAndFinish(in, remaining);

Now the file is being uploaded to Dropbox well, however following exception is raised from following statement:

while (tested.files().uploadSessionFinishBatchCheck(asyncJobIdValue).isInProgress()) {
    Thread.sleep(1000);
}

I think there are acually two problems. I seems it seems, that there are two colliding versions of the com.fasterxml.jackson library (we use the Spring Boot framework).

Nevertheless the main problem is, that the StoneSerializer.java is not able to parse the message and throws exception where the intended error message should be this:

expected field 'success', but was: 'name'
