It does indeed. Looks like the issue I'm running into was introduced by changes to LocalizedTextUtil.findResourceBundle in c826d97cafafc9ce54e15745b23cd211e233c2fa

Thanks!

> I have a few websites running under a single Tomcat packaged as separate war files. Recently, I have started to run into issues with thread starvation, which seems to stem from Struts 2. Specifically, calls to ResourceBundle.getBundle via LocalizedTextUtil.findResourceBundle end up contending on the lock for WebAppClassLoader.
> When testing things locally, it looks like the findResourceBundle is called numerous times for each <s:text> tag, with various bundle names being tried, many resulting in a MissingResourceException which does not get cached.
> I will attach a couple of thread dumps that exemplify the situation.
> If you suspect this is caused by something I am doing wrong on my end, please do let me know!
