Warnings about POJOs

Hi!

I am seeing quite a few warnings when compiling the code that say "POJO has
immutable field". What is that about?

This is telling the user that a certain type could not be analysed as
a pojo type. I assumed that we would always like to analyse things as
a pojo so this tells the user why something is not a pojo.

We could also disable the warning or demote it to INFO.
