Log messages should be swapped in LoadContexts.locateLoadingCollectionEntry(CollectionKey key):
...
LoadingCollectionEntry rtn = ( LoadingCollectionEntry ) xrefLoadingCollectionEntries.get( key );
if ( log.isTraceEnabled() ) {
if ( rtn == null )

{ log.trace( "collection [" + key + "] located in load context" ); }

else

{ log.trace( "collection [" + key + "] not located in load context" ); }

}
...

This is being added because the only way to verify the fix for JBPAPP-984/HHH-2795 is to check for these log messages and they are reversed.
