> Key: WW-2753
> URL: https://issues.apache.org/struts/browse/WW-2753
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.11.1, 2.1.2

> load of 30-40 req per sec. We are using struts 2.0.11.1, xwork2.0.4,tiles
> 2.0.6.freemarker2.3.13.
> Reporter: kirti teja
> Priority: Critical
>
> we have encountered a production incident of very slow response times over 5
> mins per page. Investagtion lead to understanding that a huge number of
> threads are getting blocked on a synchronised block in
> LocalizedTextUtil.findResourceBundle. Attached is the below stack trace. We
> have encoutnered this with two different products in our company.
