>          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

> 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 - 
>   Dtest=org.apache.nifi.processors.standard.TestWaitNotifyProtocol#testNotifyCounters 
> {code}
