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:
openjpa-kernel/src/main/java/org/apache/openjpa/conf/OpenJPAConfigurationImpl.java
...
brokerPlugin.registerInstanceFactory(BrokerImpl.class.getName(),
new BrokerInstanceFactory();
...
public class BrokerInstanceFactory implements
ObjectValue.InstanceFactory {
public Object newInstance() {
return new BrokerImpl();
}
...
> Reuse BrokerImpl objects
