> 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.
