Critical performance issue in production environment as thread dumps are
leading to OGNL 3.0 thread blocking! Website could be backed out!
------------------------------------------------------------------------------------------------------------------------------------------
Key: WW-3580
URL: https://issues.apache.org/jira/browse/WW-3580
Project: Struts 2
Issue Type: Bug
Environment: Struts 2.2.1
Reporter: Shishir Saxena
Priority: Blocker
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:
"httpSSLWorkerThread-6357-6" daemon prio=3 tid=0x01a07000 nid=0xa6
