Hi,

I am running Grouper 2.3.0.

A loader job threw this NPE:

2017-03-02 04:35:37,537: [DefaultQuartzScheduler_Worker-4] ERROR 
ChangeLogHelper.processRecords(276) -  - Error: Error processing record,

The class PassToQueueStore (in the middle of the stack trace) is my custom 
change log consumer. The line from the stack trace is

} else if
    
(changeLogEntry.equalsCategoryAndAction(ChangeLogTypeBuiltin.MEMBERSHIP_DELETE))
 {

My logic to deal with a membership delete for my provisioning use
case follows that test.

The change log record 12572825 referenced by the ERROR log entry 
is indeed a MEMBERSHIP_DELETE. 

Change log records just before it are also membership deletes for the
same group, as well as the records after it.

The memberships were being deleted because the group itself was being deleted.

The group was from the "set" of addIncludeExclude groups automatically
created and managed by a loader job. The set included

my:stem:students_systemOfRecord
my:stem:students system of record and includes
my:stem:students includes
my:stem:students excludes
my:stem:students

It was the 'students' groups for which the memberships were being deleted
when the NPE was thrown.

It appears that the NPE was thrown by 

edu.internet2.middleware.grouper.changeLog.ChangeLogTypeBuiltin.getChangeLogCategory()

Any ideas on why?

Is there something special I should be doing in my custom change log
consumer before changeLogEntry.equalsCategoryAndAction() ?

Thanks,
