actually struts is currently using ongl 2.6.11 correct? In fact the problem that you reference here http://jira.opensymphony.com/browse/OGNL-141, seems to indicate it was the 2.6.11
version of the OGNL jar that introduced the problem. Can someone verify?

I would second the idea that "this is a very important issue for my project". Not sure if this is the appropriate forum to raise this issue, but I desperately need a patch.

Does anyone know if downgrading to OGNL-2.6.10 would solve the problem? Looking at the sources the synchronization on the method object in the OgnlRuntime.invokeMethod
seems to be the only difference between the two versions...

thanks,

Hello,

We’ve been testing an application in a production environment and found a serious contention problem when the number of simultaneous requests grows. The problem seems to be related with the use of static synchronized blocks in OGNL code.

I’ve found a related issue in OGNL (http://jira.opensymphony.com/browse/OGNL-141) that is already fixed in version 2.7.2. But, another related issue (http://jira.opensymphony.com/browse/OGNL-10) is still open, although it already has a patch.

Does anyone know when Struts2 team is upgrading the OGNL version? Currently struts2 uses OGNL version 2.6.10.

This is a very important issue for my project, as it receives millions of requests per day.

Greetings,
