-----------------------------------------
Thank you [~benedict] for those findings. I think what I will try to do next is
to convince our customer that these messages logged are non-impacting
exceptions and would not pose any failures for requests (read/write) . I hope
my understanding is correct! In meanwhile, can we expect any interim fix for
this issue from community?
I once again convey my deep gratitude for all your support.

> We have hit a problem today while upgrading from 2.1.16 to 3.11.4.
> we encountered this as soon as the first node started up with 3.11.4
> The full error stack is attached - [^stack_trace.txt]
>
> The below errors continued in the log file as long as the process was up.
> ERROR [Native-Transport-Requests-12] 2019-08-06 03:00:47,135
> ErrorMessage.java:384 - Unexpected exception during request
> java.lang.NullPointerException: null
> ERROR [Native-Transport-Requests-8] 2019-08-06 03:00:48,778

> The nodetool version says 3.11.4 and the no of connections on native por t-
> 9042 was similar to other nodes. The exceptions were scary that we had to
> call off the change. Any help and insights to this problem from the community
> is appreciated.
