ICallback<Void> as a callback for DELETE request

Question

Hi,

com.microsoft.graph.http.CustomRequest#delete(com.microsoft.graph.concurrency.ICallback<java.lang.Void>) method expects com.microsoft.graph.concurrency.ICallback<java.lang.Void> as a parameter, but when you provide it, it throws an exception when processing the result, because it tries to cast com.google.gson.JsonObject to java.lang.Void, which is not possible.

Exception in thread "pool-1-thread-1" java.lang.ClassCastException: com.google.gson.JsonObject cannot be cast to java.lang.Void  

Therefore, it's not possible to provide callback methods for success and failure. Is there any workaround, or is it a bug, which is worked on?

Regards,
Dan
