@olegz I'm seeing a bunch of checkstyle violations:

> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 0.3.0
> Reporter: Oleg Zhurakousky
> Assignee: Oleg Zhurakousky
> Priority: Minor
> Fix For: 0.5.0
>
>
> Was reported in the dev thread by [email protected]
> The piece of code responsible is
> {code}
> for (int i = 0; i < SECTIONS_PER_CONTAINER; i++) {
> . . .
> if (!Files.exists(archive)) {
> continue;
> }
> . . .
> }
> {code}
> . . where continue happens without any delay.
> It was also confirmed by Adam that small Thread.slleep(..) takes care of the
> problem. What puzzles me is that the loop itself has a finite end so, need to
> look how the parent operation is invoked.
