I'm afraid, considering the error, that the problem is not with the
replication, but with the database being broken :
private void readResults( LdapSession session, SearchRequest req,
LdapResult ldapResult,
Cursor<Entry> cursor, long sizeLimit, ReplicaEventLog replicaLog
) throws Exception
{
long count = 0;
while ( ( count < sizeLimit ) && cursor.next() )
{
...
Entry entry = cursor.get();
sendSearchResultEntry( session, req, entry,
SyncStateTypeEnum.ADD );
...
private void sendSearchResultEntry( LdapSession session,
SearchRequest req, Entry entry,
SyncStateTypeEnum syncStateType ) throws Exception
{
Attribute uuid = entry.get( SchemaConstants.ENTRY_UUID_AT
); // Line 754, where we get a NPE
...
So entry is null there, and entry is directly pull from a cursor, which
is created in :
private SearchResultDone doSimpleSearch( LdapSession session,
SearchRequest req, ReplicaEventLog replicaLog )
throws Exception
{
...
Cursor<Entry> cursor = session.getCoreSession().search( req );
...
// A normal search
// Check that we have a cursor or not.
// No cursor : do a search.
Cursor<Entry> cursor = session.getCoreSession().search( req );
// Position the cursor at the beginning
cursor.beforeFirst();
...
readResults( session, req, ldapResult, cursor, sizeLimit,
replicaLog );
