Craig Russell commented on OPENJPA-160:

The real cost according to the trace is in the dynamically created class, not 
in BrokerImpl<init>.

I don't get it either, except to think that the implementation of the 
dynamically created class uses reflection itself, which is slow.

To see if this is the case, we'll need to create a real compiler-generated 
factory, like this:

            new BrokerInstanceFactory();
       public class BrokerInstanceFactory implements 
ObjectValue.InstanceFactory {
                public Object newInstance() {
                    return new BrokerImpl();

> Reuse BrokerImpl objects
