[eclipselink-users] Stale Data, NPE on validateCache()

[trispad <tristan.paddock@xxxxxxxxx>]

I am having a problem with stale data.  I use multiple ClientSessions that
hang off of the same ServerSession.  However, it appears that commits via a
UnitOfWork from a ClientSession are not updating the cache and stale data is
received when a query is preformed.  I have added in a call to
validateCache() on the ServerSession(), however this throws a NPE.  Here is
the stack trace I get:

java.lang.NullPointerException
	at
org.eclipse.persistence.internal.sessions.IdentityMapAccessor$1.iterate(IdentityMapAccessor.java:988)
	at
org.eclipse.persistence.internal.descriptors.DescriptorIterator.startIterationOn(DescriptorIterator.java:470)
	at
org.eclipse.persistence.internal.sessions.IdentityMapAccessor.validateCache(IdentityMapAccessor.java:1002)
	at
org.eclipse.persistence.internal.sessions.AbstractSession.validateCache(AbstractSession.java:3211)

It appears that one of the IdentityMaps from the Descriptor is null.  I am
at a loss trying to figure out why this is happening.  I have tried setting
the caching default to Full and None with the same result.  Let me know what
other information I can provide.
