This is a clone of Issue:
CLONE - Struts 2.3.8 threads BLOCKED in com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration(WW3971)
We followed the instructions in the original ticket and installed version 2.3.12, however we still see the same problem there. Under load we see several threads hung on getConfiguration. The only alternative is to restart the app.
"[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00007f70b55f4800 nid=0x1aa waiting for monitor entry [0x00007f70b3916000]
java.lang.Thread.State: BLOCKED (on object monitor)
- waiting to lock <0x000000051b3214f0> (a com.opensymphony.xwork2.config.ConfigurationManager)
Can we you please investigate this?
