-----------------------------------
Hi [~csomaati] - to be honest, I don't know that this is really needed.
Can you articulate a usecase where we need multiple values for the same key?
I've never quite understood why anyone would file a JIRA for not being able to
separate values with the delimiter used to separate the pairs.
I also agree that it isn't clear whether the problem is not being able to have
commas in the value or whether it is desired to have multiple values for the
same key.
Again, we need an actual usecase for what this param is intended for - that
being, the ability to provide token session clients with hints that they can
use when interacting with services through a JWTProvider protected topology.

> If in case in client data , a key has got list of comma separated values,
> then only the first value in the list is considered in the response.
> Should be able to differentiate between commas within values and comma used
> as delimiter for key value pair. When used escape character for comma within
> values list is also not working.
>
> For example
> Configured a comma separated list of value for a key as below
> {code}
> <name>knox.token.client.data</name>
> <value>key1=value1,value2,value3,key2=value4</value>
> {code}
> *Response is as follows:*
