-------------------------------------------------------
Commit 59ff1b6561863c500283d665e9675979b065e78b in nifi's branch
refs/heads/main from jsteinebrey
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=59ff1b6561 ]
NIFI-9677 Fixed issue that an empty JSON array causes flow file to be
considered unmatched even though it should be considered as a match.
Refactored to avoid streaming over the list twice.
Tweaked unit test, so it works in NiFi 1.x also.

> Input JSON generated by GenerateFlowFile processor looks like this (actually
> I just added a currencies array under each record in addition to the "Record
> Update Strategy - Replace Existing Values" example here
> [https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.15.0/org.apache.nifi.processors.standard.LookupRecord/additionalDetails.html).]
> *Note:* for the first record currencies array is empty.

> Once I execute the LookUpRecord processor for the flow file, language look up
> works fine, but the look up for currencies and regions do not work.

> *Note:* in case the 1st currencies array is not empty but contains \{
> "currency": "EUR" }, \{ "currency": "USD" }, all look up works fine. But a
> missing data seems to break the next evaluation of the record path.
> Please find the template for reproducing the issue enclosed as
