> 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).
