Jasper Rosenberg commented on WW-4489:
--------------------------------------
Well, all I was trying to point out is that the current pattern matches
anything before \\bclass, because of the "|.*|" section. I figured that wasn't
intentional, but wasn't sure what the intent was.

> Key: WW-4489
> URL: https://issues.apache.org/jira/browse/WW-4489
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.3.20
> Reporter: Jasper Rosenberg
> Priority: Minor
> Fix For: 2.3.24
>
>
> The current pattern that matches class expressions looks like:
> {code:java}"(.*\\.|^|.*|\\[('|\"))\\bclass(\\.|('|\")]|\\[).*"{code}
> However, as far as I can tell, this is completely equivalent to:
> {code:java}".*\\bclass(\\.|('|\")]|\\[).*"{code}
> Not sure if this is a bug, or an improvement.
