---------------------------------------------------------------
Sorry Indeed I could provide a an example of what cause this.
So this classes are generated of a proto that looks like this (basically any
map or repeated "Message" will cause this):
{code:java}
syntax = "proto3";
package com.xyz.test;
message Test {
map<string, SInt64Value> fldMap = 1;
repeated SInt64Value anotherList = 2;
}
message SInt64Value {
sint64 intVal = 1;
}
{code}
It is stored as a BLOB in the DB.
This is the generated class from protoc [^TestCopy.java]
So looking at it, the fields are of types com.google.protobuf.MapField and
java.util.List
So maybe I'm wrong and the problem would be just for the MapField and not the
java.util.List
Maybe the reason for this issue is that one could MapField to implement some
sort of map, but it does not so maybe that's why it requires this special
handling

I'll copy/update the ticket with the generated class from protobuf in a little
bit

This because I would expect MapField to implement some sort of map, but it does
not
