JBoss 7.1 and EAP 6 support

I understand that keeping up with a new version can be difficult. Having said that, JBoss 7.1.1 Final was released in early March and Enterprise Application Platform (EAP) 6, the fully supported version by RedHat which is based on 7.1, has been released recently. I would really like to use ObjectDB since I believe that I will need the performance gains you show. Is there a plan to support this version of JBoss? I would also like to ask when but I know timeframes are not really known in advance, let me just state that my project will need to go live in about 4 weeks. #1 2012-07-15 20:44 I understand that keeping up with a new version can be difficult.

Empty query results after JAR creation

Hi, I struggle with a strange issue. I've embedded ObjectDB in a small application to query cases. Within Netbeans everything works fine but when I create a  JAR File and executed via "Java -Jar xyz.jar", I get either empty results or on some cases a "NoResultException" which appears to report the same issue. I've created a small test case (attached zip file) with sample DB to reproduce the issue.  #1 2012-04-24 04:03 Hi, I struggle with a strange issue.

significant performance decrease

we are using objected in embedded mode (on OS X and WINDOWS). The database increased now to around 400000 entities of one class (database file size around 1.5 GByte). The response time of standard queries increased with this database size to an unacceptable rate (several seconds compared to around 30% when the number of entities was just half of the current). We tried to optimize the cache settings, current objectdb.conf is: <!-- ObjectDB Configuration --> <objectdb> ... > <quota directories = "5" files = "20" disk-space = "5mb" /> ...
