-----------------------------------

This is going to be replaced by the approach in [#2748|https://github.com/apache/nifi/pull/2748]

> I am using the ReplaceText processor to take a string input (example:   {"name":"Smith","middle":"nifi","firstname":"John"} ) and change all the filed names to all uppercase.
> Using above input as an example, I expect output like {"NAME":"Smith","MIDDLE":"nifi","FIRSTNAME":"John"}
> I expect I should be able to do this with ReplaceText processor; however, I see some unexpected behavior:
> -------
> Test 1:  (uses EL in the replacement value property)
> Search value:  \"([a-z]+?)\":\"(.+?)\"
> Replacement Value: \"*${'$1':toUpper()}*":\"$2\"
> Result: {"NAME":"Smith","NAME":"nifi","NAME":"John"}
> -------
> Test 2:  (Does not use EL in the replacement Value property)
> Search value:  \"([a-z]+?)\":\"(.+?)\"
> Replacement Value: \"new$1":\"$2\"
> Result: {"newname":"Smith","newmiddle":"nifi","newfirstname":"John"}
> --------
> As you can see if I use a NiFi expression Language statement in the Replacement Value property it no longer iterates as expect through the various $1 captured values. It repeatedly uses the EL result from the first EL evaluation in every iteration while $2 correctly iterates through the search values.
