[news.eclipse.rt.eclipselink] FileNotFoundException: tempToDelete.xml (

[hansharz_bugzilla@xxxxxxxxxxxxxx (Hans Harz)]

Hello,

this strange error appears quite regular after switching from toplink to 
eclipselink. Unfortunatly it's not possible to reproduce in a unit test, 
but around every third time I start our application I get this here:

Internal Exception: java.lang.RuntimeException: Exception 
[EclipseLink-7018] (Eclipse Persistence Services - 1.1.2.v20090612-r4475): 
org.eclipse.persistence.exceptions.ValidationException
Exception Description: File error.
Internal Exception: java.io.FileNotFoundException: 
C:\acrolinxIQ\server\bin\tempToDelete.xml (Access is denied)

I stepped through the eclipselink sourcecode and I really discovered, that 
a xml file is written to hard disk only to clone an object when 
TABLE_PER_CLASS inheritance is used.

This is the method: 
org.eclipse.persistence.internal.jpa.metadata.xml.XMLEntityMappings.reloadXMLEntityMappingsObject(XMLEntityMappings)

I'm working with a huge legacy system, and maybe it's a bug on my side, 
but why you don't use a memorystream or something comparable fast.

Any comments?

best regards,
hans
