Grouper Users - Open Discussion List

["Hyzer, Chris" <>]

It looks like the stack mysteriously ends.  Does this help?

http://stackoverflow.com/questions/2411487/nullpointerexception-in-java-with-no-stacktrace

Can you add this option to the JVM and capture another stack?

-XX:-OmitStackTraceInFastThrow

Or do you think there is another reason the stack is not there?

Thanks
Chris

Subject: [grouper-users] deleteGroupsIfNotUsed throws NPE in loader job

Hi,

I am running Grouper 2.3.0. The API is up-to-date with patches as of
this morning.

(This NPE error is distinct from the one I reported a week ago.)

The Grouper loader is throwing this error:

2017-03-20 13:10:18,638: [DefaultQuartzScheduler_Worker-3] ERROR 
GrouperLoaderType.syncGroupList(1422) -  - Error on group:

There are no other log entries that indicate any type of issue with that
group.

Any ideas?

Thanks,
