> {{CommonTestUtils.createTempDirectory()}} encourages a dangerous design pattern with potential concurrency issues in the unit tests as well as the need to cleanup the created directories.
> Instead, it should be solved by using the following pattern:
> {code:java}
>         @Rule
>         public TemporaryFolder tempFolder = new TemporaryFolder();
> {code}
> We should therefore remove {{CommonTestUtils.createTempDirectory()}}.
