Nested exceptions to follow:
----------- Debug information
There is no ENTRY_CSN in the entry object hence returns a null.
in private void updateCsnIndex( Entry entry, String id ) throws Exception
{
String entryCsn = entry.get( SchemaConstants.ENTRY_CSN_AT ).getString();
entryCsnIdx.drop( id );
entryCsnIdx.add( entryCsn, id );
}
---- The 'entry' object is the following.
dn[n]: ou=system
objectclass: top
objectclass: organizationalUnit
description: The System context entry
contextCSN: 20130826073011.649000Z#000000#001#000000
entryParentId: 00000000-0000-0000-0000-000000000000

entryUUID: ff64c5d1-d2ec-441e-a1c0-306c89de2264
modifyTimestamp: 20131102091722.945Z
I am not sure if the bug is ENTRY_CSN was not found, or this is a valid
case and the f() should check for NULL following entry.get()
Using default instance from fresh install this case doesn't show up.
I tested with adding a check for null and just returned and shutdown appears to
finish without error.
