EJB3 "clear" operation required in EJB3 SLSB Pools like EJB 2.x

There was a "clear" operation on pool in jmx-console for SLSB 2.

However, for EJB 3 it does not exists.

I even do not see anything like flush in the API of ThreadLocalPool or StrictMaxPool and its super class AbstractPool

However, I see that a person has customized the pool having timeout parameter which clears pool :
