> Fix flaky test TestClassFinder#testClassFinderDefaultsToOwnPackage
> -------------------------------------------------------------------
>
> Key: HBASE-25370
> URL: https://issues.apache.org/jira/browse/HBASE-25370
> Project: HBase
> Issue Type: Test
> Components: test
> Reporter: Adam Wang
> Assignee: Adam Wang
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.2.7, 2.3.4, 2.5.0, 2.4.1
>
>
> The test {{TestClassFinder#testClassFinderDefaultsToOwnPackage}} compares two
> sets from {{allClassesFinder.findClasses}}. However, the function
> {{allClassesFinder.findClasses}} does not return the deterministic order
> result. From code trace, the root cause is at
> {{ClassFinder.findClassesFromJar}} and {{ClassFinder.findClassesFromFiles}}.
> They use {{HashSet}} to store {{classes}} and {{listFiles}} to get file
> array. However, {{HashSet}} and {{listFiles}} do not guarantee that order,
> and the assertion can fail if the order differs.
