Activerecord getting in the way of json-jruby

I would like to use json-jruby with activerecord but it seems as if i am
running into issues with activerecord loading active_support which has
it’s own json implementation.

What makes matters worse is I am running into this redundant UTF-8
sequence issue with active_support json which does not happen with
json-jruby.

INFO: ArgumentError - redundant UTF-8 sequence:

Any ideas?

thx.

I was able to get around this problem by including ‘json-jruby’ after
activerecord and explicitly requiring ‘json/pure’. What is the
difference between json/pure and json/ext within jruby?

thx.
