You can use Instrumentation.getObjectSize() to obtain an estimate of the storage consumed by an object.
You can use ea-agent-loader
With it loading an agent in runtime will look like:
public class HelloAgentWorld
{
public static class HelloAgent
{
public static void agentmain(String agentArgs, Instrumentation inst)
{
System.out.println(agentArgs);
System.out.println("Hi from the agent!");
System.out.println("I've got instrumentation!: " + inst);
}
}
public static void main(String[] args)
{
AgentLoader.loadAgentClass(HelloAgent.class.getName(), "Hello!");
}
}
It may be due to this breaking change in Eclipse 3.6:
EDIT:
Looks like it definitely is. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=309074. Here's the fix:
In the "Customize Perspective" dialog, go to the "Command Groups Availability" tab and check "Team" and "SVN".
In Eclipse Mars.2 (4.5.2) this is under Window->Perspective->Customize Perspective... dialog, "Action Set Availability" tab. (Try to restart Eclipse if it doesn't work after you change it). Customize Perspective dialog screenshot
As you said, the callback method is called the second time, if the entity is detached or fetched again from DB.
I cannot explain it exactly, but can think of the scenario described here, when no dirty fields are identified before the second save() call and thus the @PreUpdate callback not called. Or it may be simply a bug within your version of EclipseLink.
