Summary:
com/opensymphony/xwork2/util/FileManager.fileNeedsReloading lead to high cpu
using
Key: WW-4281
URL: https://issues.apache.org/jira/browse/WW-4281
Project: Struts 2
Issue Type: Bug
Components: Annotations
Affects Versions: 2.3.16, 2.2.3
Environment: OS : IBM AIX 6.1
CPU : ppc 64-bit
JDK : IBM J9 VM 1.6 SR14 64-bit
WebLogic Server : 11gR1 ps5(10.3.6)
Apache Tomcat : 7.0.42
Struts 2.2.1、2.2.3、2.3.16
Reporter: Chris Tian
We found high cpu using when we used loadrunner to make a load test to our
application which is deployed on tomcat and weblogic server, then we took some
thread dump (kill -3 pid), the java virtual machine generated some files which
name liked javacore.<date>.<pid>.<serial number>.
By analyzing there javacore files, we found some threads were reloading class,
it caused high cpu using.
