This is exactly the same issue as reported here for the python sdk

Confirmed that the Raw response DOES contain the expected payment detail. The issue is caused by erroneous unmarshalling here:

BunqModel.java:

protected static BunqResponse fromJson(Class classOfObject, BunqResponseRaw responseRaw, String wrapper) {
JsonObject responseItemObject = getResponseItemObject(responseRaw); // RAW RESPONSE LOOKS OK, CONTAINS THE PAYMENT DETAIL
JsonObject responseItemObjectUnwrapped = getWrappedContent(responseItemObject, wrapper);
T responseValue = gson.fromJson(responseItemObjectUnwrapped, classOfObject); // HERE IT GOES WRONG, PAYMENT DETAIL IS EMPTY
return new BunqResponse(responseValue, responseRaw.getHeaders());
}

Update:
The bug is caused by a difference between the Java object hierarchy and the hierarchy in the api response. The payment object is nested twice.

Unmarshalling the raw reponse as follows resolves a Payment included in the first 'inquiry_result'.

JsonObject target = jsonObject.getAsJsonArray("Response")
                        .get(0)
                        .getAsJsonObject()
                        .getAsJsonObject("BunqMeTab")
                        .getAsJsonArray("result_inquiries")
                        .get(0)
                        .getAsJsonObject()
                        .getAsJsonObject("payment")
                        .getAsJsonObject("Payment") // this is were the bug caused by mapping error java vs. Json is...
        );
        Payment payment = gson.fromJson(target, Payment.class); //now unmarshals to correct object
