> 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.
