Hi there, I hope that you are doing well!
I'm encountering some NullPointerException when trying to deserialize my
protobuf message using the parseFrom method from my generated class (you
can have a look at the stack below). Code has been generated using protoc
3.7.0, and we are currently using protobuf 3.8.0 libraries at runtime.

NullPointerException are not happening all the time. Usually, it works at
the beginning and at some point everything fall apart and all
deserialization are ending in a NullPointerException. This issue is only
happening in production after some time, I tried to replicate the problem
locally and failed to do so.
Could it be an issue fixed in a more recent releases or already seen by
someone ?
Any input would be appreciated :)
Thanks in advance for your help!
