Lukasz Lenart commented on WW-4489:
-----------------------------------
You can access class as follow
{code}
#application['class'].classLoader
#session.class.classLoader
{code}
so it must always have a prefix but what if user passes
{{styleClass.internal=true}} query parameter?
> Simplify DefaultExcludedPatternsChecker class pattern

> 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.
