---------------------------------
[~Valvrave] Please do not set fix versions. We will set them when we identify
which release something will be on which is generally done when that thing is
coded, reviewed, and being merged.
> Fixed Possible Json Ordering Permutations Problem in Tests
> ----------------------------------------------------------

> Key: NIFI-10630
> URL: https://issues.apache.org/jira/browse/NIFI-10630
> Project: Apache NiFi
> Issue Type: Test
> Components: NiFi Registry
> Affects Versions: 1.18.0
> Environment: Apache Maven 3.6.3
> Java version: 11.0.16, vendor: Ubuntu, runtime:
> /usr/lib/jvm/java-11-openjdk-amd64
> Default locale: en_US, platform encoding: UTF-8
> OS name: "linux", version: "5.4.0-124-generic", arch: "amd64", family: "unix"
> Reporter: Boyu Li
> Priority: Minor
>
> The test file
> {code:java}
> nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors
> org.apache.nifi.processors.standard.TestWaitNotifyProtocol
> {code}
> has flakiness with the below three tests.
> {code:java}
> testNotifyAttributes
> testNotifyCounters
> testNotifyFirst
> {code}
> The test flakiness is due to comparisons between Json Strings and outputs from
> cacheEntry.getValue() which is an Object AtomicCacheEntry<String, String,
> Long>
> However, JsonObject does not guarantee entry orders, its object is an
> unordered set of name/value pairs, and internal permutations may occur in the
> output as JSON String.
>
> *Steps to reproduce the failure:*
> The flakiness was found with
> [NonDex.|https://github.com/TestingResearchIllinois/NonDex)]
> After installing NonDex and run the following code.
> {code:java}
> cd nifi
> mvn install -pl
> nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors -am -DskipTests
> mvn -pl nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors
> edu.illinois:nondex-
> maven-plugin:1.1.3-SNAPSHOT:nondex -
