-------------------------------
Resolution: Fixed
> Make excluded package exemption logic more strict
> -------------------------------------------------
>
> Key: WW-5288
> URL: https://issues.apache.org/jira/browse/WW-5288
> Project: Struts 2
> Issue Type: Improvement
> Components: Core
> Reporter: Kusal Kithul-Godage
> Priority: Minor
> Fix For: 6.2.0
>
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> Following on from the discussion in the comments on WW-5268 - exempting
> classes from excluded packages should only be done if unavoidable.
> Given this, I realised we should make the exemption logic more strict to
> prevent incorrect use and inadvertent exempting of more OGNL expressions than
> intended.
> * Currently, the exempted classes also match against superclasses. This is
> unnecessary and we can match against only the specific class.
> * Currently, an exemption against either the target or member class suffices.
> This can be made more strict by requiring an exemption for the class which
> matches the excluded package specifically, which could be either or both.
> * The JavaDoc for the options should be very explicit in what each
> configuration option achieves to prevent incorrect uses.
