Sporadic EntityNotFoundExceptions after upgrading to 2.7.7

[Christie]

Hi,

I am getting sporadic EntityNotFoundExceptions on Ebean 2.7.7.  I have a standalone Java method that imports a large number of text files into a database. This method does not do any entity deletes, it only adds entities to the DB.  If I run this import method multiple times, it will crash on different lines of import text (it's never the same lines), but the method it crashes on is usually the following:

[com.widget.importing.Importer]08/6/2012 21:21:14 PM ERROR: javax.persistence.EntityNotFoundException : Bean has been deleted - lazy loading failed
      at com.avaje.ebean.bean.EntityBeanIntercept.loadBeanInternal(EntityBeanIntercept.java:535)
      at com.avaje.ebean.bean.EntityBeanIntercept.loadBean(EntityBeanIntercept.java:499)
      at com.avaje.ebean.bean.EntityBeanIntercept.preGetter(EntityBeanIntercept.java:623)
      at com.widget.importing.Widget._ebean_get_volumeAmount(Widget.java:4)
      at com.widget.importing.Widget.getVolumeAmount(Widget.java:149)
      ....

volumeAmount is a Double that apparently is getting lazy loaded, so the error message is a little deceiving (the lazy load failure was not on an entity and the Widget itself does still exist in the DB).

I have gotten this error once or twice during the import method when trying to access an actual entity, but haven't been able to reproduce it to check to see that the entity actually is there (I'm pretty sure it would be since this method doesn't do any deletes).

I have verified that this happens in 2.7.7 and 2.7.6-SNAPSHOT.  When I revert to 2.7.5 the problem disappears.  Any ideas what could be the issue?  I browsed the SVN logs for EntityBeanIntercept and it looks like a number of changes have been made since 2.7.5.  Since I can't reproduce the issue reliably I'm not sure if this is even fixable on your end.

Thanks,

Christie

Hmmmm …..

 

Is the Widget the root entity you loaded, or is it itself the property of another entity?

If so, does the root entity contain two (or more) Widget properties?

 

Ciao,

Where there any updates to this issue?

Thanks, Rob.

Sorry - been working on other areas of the project.

After reverting back to 2.7.5 I ran the import a couple times.  Unfortunately it crashed on one of those imports, so it wasn't anything to do with the 2.7.7 upgrade.  It isn't crashing on the getVolumeAmount() call anymore, but on a call to an entity off the Widget entity (Widget contains an object of type ItemPackage).  The Widget is the root entity loaded, and does not contain any other Widgets.  Just an ItemPackage (and some other objects and fields).

I put in some debug code and put a breakpoint in the Ebean source code to try to get an idea of what is wrong but of course when I did that it chose not to crash.  :)  I'm not sure what to do about it so I've put it on the back burner for now.

Ok, thanks.

I never did get to the bottom of it.  I "solved" it by wrapping the problem method in a try-catch and then calling the method a second time if the exception was thrown.

The same error is occurring to me, sporadically.

And I'm not deleting anything.

Thanks!

That exactly the same solution I did.
