This problem appears to be AT-SPI (accessibility) related. stracing netbeans 7.1 shows that the JVM is attempting to connect to a separate dbus session bus. However, the dbus daemon associated with that bus isn't running.
If you run "gnome-control-center", select "Universal Access", and enable a setting (for example the screen reader), you'll then find a number of new spi processes running including: at-spi2-registryd ? at-spi-bus-launcher dbus-daemon (a 2nd instance specifically for at-spi seemingly). If you now attempt to start netbeans, you'll find the JVM crashes with a core dump. Killing those processes returns us to the initial "Couldn't connect to accessibility bus:" warning. So, there seems to be a problem with openjdk's use of at-spi.
