: Ok I think I know where the problem is ... : It's the constructor used by SolrCore in r772051
Ughhh... so to be clear: you haven't been using Solr 1.4 at any point in this thread? that explains why no one else could recreate the problem you were describing. For future refrence: if you aren't using the most recently released version of Solr when you post a question about a possible bug, please make that very clear right up at the top of your message, and if you think you've found a bug, pelase make sure to test against the most recently released version to see if it's already been fixed. : PS : should I fill some kind of bug report even if everything is ok now ? (I'm : asking because I didn't see anything related to this problem in JIRA, so maybe : if you want to keep a trace...) If you can recreate the problem using Solr 1.3, then feel free to file a bug, noting that it was only a problem in 1.3, but has already been fixed in 1.4 ... but we don't usually bother tracking bugs against arbitrary unlreased points from the trunk (unless they are current). I'm sure there are lots of bugs that existed only transiently as features were being fleshed out. -Hoss
