Okay, fair enough. Definitely looks odd and I will adjust that.
> Bundle version number should not be compared as a simple String

> Key: MINIFI-415
> URL: https://issues.apache.org/jira/browse/MINIFI-415
> Project: Apache NiFi MiNiFi
> Issue Type: Bug
> Components: Agent Configuration/Installation
> Affects Versions: 0.3.0
> Reporter: Koji Kawamura
> Assignee: Aldrin Piri
> Priority: Minor
>
> MINIFI-408 added support for picking the latest bundle version automatically
> if there are multiple versions for the same Nar. However, it compares version
> as simple Strings and may not be able to pick the latest one semantically.
> https://github.com/apache/nifi-minifi/pull/99/files#diff-c7d8398db8540d6e85f1a9207438ebddR138
> Following code shows the problematic inputs and possible solution. Current
> implementation picks "1.0.9", and using Version class, it can pick "1.0.12".
