Description

1. org.apache.nifi.processors.standard.TestSegmentContent.test

This is a flaky test, it can pass mvn test while but when run using the tool NonDex, it fails. NonDex is a tool that will introduce non-determinism in certain java collections.

The test shows below:

[ERROR] Failures:
[ERROR]   TestSegmentContent.test:51 FlowFile content differs from input at byte 0 with input having value 1 and FlowFile having value 9

Steps to reproduce the failure:

1. Run the following command in nifi:
2. First, build the module:

mvn install -pl nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors -am -DskipTests -Drat.skip

1. Then run the test using NonDex

1. 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.TestSegmentContent#test

The result will be saved under the module folder in .nondex
