Hi there!

I am pretty new to hibernate but have been asked to resolve this issue with the reflection optimizer getting disabled when loading select domain objects.

I have already looked thru the faqs and the online reference doc to realize that for certain objects Reflection Helper gets disabled and the objects are loaded using reflection.

However, to make our application performant, I would like to do whatever we can on our part to prevent Reflection Helper from getting disabled on these object.

Can someone provide me with some clues as to how to proceed further to prevent reflection helper from getting disabled. Is there some way to order the loading of domain objects? (I am guessing, that may resolve the problem, as most of the objects below are related to each other...)

Any help would be greatly appreciated.

Plese show java class and mapping for caw.b3xt.domain.agreement.ClauseDestination


mapping and java class for caw.b3xt.domain.rate.CarrierRate....
But you can read .... :)
(Ljava/lang/Object;[Ljava/lang/Object;)V) Expecting to find array of objects or arrays on stack
so as I got you have a setter with Object argument instead of expected array of objects.


java class and mapping for caw.b3xt.domain.user.User


CGLIB expects array of objects or arrays for argument of some setter.

It is not the best solution, but if you don't want to change anything in the java code set in the mappings access="field" instead of default access="property". If it helps you, return back all default access="property" and try to find error-prone java class setters and getters.

Hi,

Below is the code for Clause Destination that caused the Reflection Helper to throw a NPE.....And I will try out setting access to fields and see what happens.

Thanks.




public class ClauseDestination extends IntegerKeyImpl implements Auditable
{

/**

*/
public ClauseDestination()
{
super();
//setPersisted();
}

public ClauseDestination( AgreementDestination dest )
{
//setTransient();

setAgreementDestination( dest );
}

// --------------------------------------------

public int getSequenceNumber()
{
return sequenceNumber;
}

/**

{
this.sequenceNumber = sequenceNumber;
}
