Hi, Recently I tried to upgrade Jasperserver Pro 5.1 to 5.2 - from WAR file distribution running on Tomcat7 (OpenJDK 1.7 or Oracle Java 1.7, i tried both) with Postgresql 9.1 as Jasper database. After successfully running script js-upgrade-samedb.sh - no errors, all done starting tomcat is getting stuck infinitely after reaching Creating ActionModelService object. Creating action model infrastructure. In a catalina.out logfile, jasperserver.log log is empty It is not possible to stop tomcat then, only kill -9 works. I have to restore from backup, to 5.1 which is working without problem. Anyone experiened similar problem? Any solution ? Regards Rafał
