Hi
My web application based on Struts 2.2.1 is using OGNL 3.0. This web
application is rolled into production; however, due to serious performance
considerations the website is in danger of being rolled back. The thread
dumps indicate 'BLOCKING' at ognl.OgnlRuntime.invokeMethod
(OgnlRuntime.java:804).
The thread trace is as:
