Hello, I was working with ireport 5.1.0 in my ubuntu desktop 12.04, but suddenly it stops working the preview feature. When i click preview it just displays a error message with 'null' as message and get frozen, I cannot close the error message window or close the ireports, i have to kill the process. I tested with the sample reports and they are not working either. My initial guess was that it breaks due a ubuntu java update. The version i currently have is java version "1.6.0_27" OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1ubuntu0.12.04.2) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) But i tried downloading the oracle jdk1.7.0_25 and using the parameter --jdkhome and the issue still there I've checked the ~/.ireport/5.1.0/var/log/messages.log but din't find any trace related to the last preview action, attached is the tracelog for a quick report i generated using the wizard.
