Hi,

I'm getting this exception when using a Lucene index and don't have any
idea why I might be getting it:

SEVERE: null

I'm using Neo4j 1.7 on a Linux machine.
Any clues?
Thanks!

Pablo

Hi Pablo,

That's most likely caused by a version mismatch. What Neo4j version was the
store created with, and which version are you using to access it? Are you
running embedded?

Thanks,
David

Hi David,

Thanks for the quick response. You're right!
I was combining two different programs and one of them has a version around
1.5 whilst the other one is built with 1.7, (silly me... :P )
I probably corrupted the DB then, because I was adding new content when
using the program compiled with 1.5 to a previously created DB with 1.7
version ....

Cheers,

Pablo

It shouldn't be corrupted. It's just that 1.7 uses a later Lucene version
that 1.5 can't read.
