Thanks Derek for your quick answer!
Do you have a reason in mind for trying protobuf-java >= 3.17 ? I mean, was
there any important changes around this release that might be related to
this issue ?
I will probably have to fight very seriously to push for an upgrade of the
version we are currently using in production, so if you have any pointers
to a changelog / commit, that would be awesome!
