> This is a flaky test, it can pass mvn test while but when run using the tool
> [NonDex|https://github.com/TestingResearchIllinois/NonDex], it fails. NonDex
> is a tool that will introduce non-determinism in certain java collections.
> The test shows below:
> {code:java}
> [ERROR] Failures:
> [ERROR] TestMergeContent.testDefragmentMultipleMingledSegments:1028
> FlowFile content differs from input at byte 0 with input having value 65 and
> FlowFile having value 78
> {code}
> *Steps to reproduce the failure:*
> # Run the following command in nifi:
> # First, build the module:
> {noformat}
> mvn clean install -pl
> nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors -DskipTests
> -Drat.skip -am {noformat}
> # Then run the test using
> [NonDex|https://github.com/TestingResearchIllinois/NonDex]
> {noformat}
> mvn edu.illinois:nondex-maven-plugin:1.1.2:nondex -pl
> nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors
> -Dtest=org.apache.nifi.processors.standard.TestMergeContent#testDefragmentMultipleMingledSegments{noformat}
