Hello Sebastian,
I did some trials right now, and the only thing I can tell so far is that it
might be related to things I do in the module I am working on.
It did happen in my H2 instance, but not on my PostgreSQL instance so far.
It seems it does happen after a delete of a context has failed.
In that module, I work with contexts that I sometimes delete. To do so, I did
declare:
@Inject
private ContextService contextService;
and the deleting code is simply:
contextService.removeContext(context);
I did notice that sometimes, this "contextService.removeContext(context)" does
fail, but it seems it happens only with H2, not with PostgreSQL, and I have no
further information so far. As the removeContext() method don't throw any
exception, but just return a boolean, I will try to see if any error is logged,
next time it happens.
As you tell me it is not something that others have experienced, I will try to
better understand what happens. And then I'll let you know.
I do ask myself if this could happen in this situation:
- server is started
- a browser displays the Marmotta GUI (from which I delete a context)
- then the server is restarted
- without reloading the GUI page, I use the 'delete' functionality
Thank you
Fabian

Hi Fabien,
this looks like a weird error (the kind where a developer typically throws
a ShouldNeverHappenException ;-) ). How can it be reproduced reliably? Is
there a certain seqeunce to do so? Is it "random"? Does it really only
happen with H2?
Greetings,
Sebastian
