Was this is a change in the way that ReplaceText behaves or was this unit
test incorrect before? Is there a way to obtain t he output "a\$b" from
ReplaceText now?
> ReplaceText processor does not properly iterate multiple replacement values

> Key: NIFI-4272
> URL: https://issues.apache.org/jira/browse/NIFI-4272
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.1.0, 1.2.0, 1.3.0
> Reporter: Matthew Clarke
> Assignee: Otto Fowler
> Priority: Major
>
> 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.
