> 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!
