--------------------------------------------------------------------
Because I needed to debug the connectivity issues, but I was getting
ODataDeserializerException stack trace in logs, which is not helpful.
So I figured that I can intercept error message body before
odataClient.getReader().readError(entity, contentType)
is called, which throws ODataDeserializerException and masks real cause from
logs. And if deserialization exception happens I will instead display raw
message in logs, which is much more helpful.
Update:
Test for this specific case is added to ErrorTest class.
