Re: [Virtuoso-users] V7.0.0/Jena provider bug with SELECT/LIMIT Results off by one

[Hugh W. <hwi...@op...>]

Hi Erich,

Are you saying if the same query is run against Jena 2.10.x of Jena 2.6.x the result set is correctly returned ? We are about to test this new Jena 2.11 release to see whats new and if there are issues with the current provider (particularly the 2.10.x provider) to determine compatibility or if a new provider needs to be created ...

Best Regards
Hugh Williams
