Arvid Heise commented on FLINK-23022:
-------------------------------------
Sorry you are right, it definitively loads from flink cl first. So we can leave
the ticket as is.
Still I'd like to limit it to a small white-list of classes instead of complete
packages.

> Key: FLINK-23022
> URL: https://issues.apache.org/jira/browse/FLINK-23022
> Project: Flink
> Issue Type: Bug
> Components: API / Core
> Reporter: Dawid Wysakowicz
> Priority: Major
>
> The options {{plugin.classloader.parent-first-patterns}} are documented as
> all patterns that are put there should be loaded from the Flink classloader
> instead of the plugin classloader.
> However, the way they work is that they define a set of patterns allowed to
> be pulled from the parent classloader. The plugin classloader takes
> precedence in all cases. And a class can be loaded from the parent
> classloader only if it matches the pattern in one of the aforementioned
> options.
