Hello, While I could reproduce the issue with java-atk-wrapper 0.30, I can not reproduce it with java-atk-wrapper 0.33. I had reported the issue on https://bugzilla.gnome.org/show_bug.cgi?id=698095 , and it was reported as fixed.
Perhaps it is the time to consider re-enabling accessibility in /etc/java-7-openjdk/accessibility.properties ? (wily has java-atk- wrapper 0.33) Samuel ** Bug watch added: GNOME Bug Tracker #698095 https://bugzilla.gnome.org/show_bug.cgi?id=698095 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to java-atk-wrapper in Ubuntu. https://bugs.launchpad.net/bugs/935296 Title: java-atk-wrapper prevents java applications from starting Status in java-atk-wrapper package in Ubuntu: Confirmed Status in openjdk-6 package in Ubuntu: Fix Released Status in openjdk-7 package in Ubuntu: Fix Released Status in java-atk-wrapper source package in Precise: Confirmed Status in openjdk-6 source package in Precise: Triaged Status in openjdk-7 source package in Precise: Triaged Status in java-atk-wrapper package in Debian: Fix Released Bug description: default java at command line is still java6. invoke java from command line, and minecraft fails to start, usually with no message, but there is some variety.
