Thanks, Lukasz Lenart
This issue had been resolved by setting these three parameter to false, then
the performance improved, the response time has been down, the cpu using has
been down.
Thanks Again.

> 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.
