Description gragon 2015-04-19 04:11:06 UTC

Build: NetBeans IDE 8.0.2 (Build 201408251540)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.31-b07, Java(TM) SE Runtime Environment, 1.8.0_31-b13
OS: Linux

User Comments:
farseenabdulsalam: I didn't notice anything wrong. But this error showed up in the status bar and I though I should report it.

gragon: I launched Netbeans.  Then I selected the third (last) tab in a TabPane (JavaFX).

farseenabdulsalam: I started up NetBeans 8. Monet scenbuilder plugin was already installed. A JavaFX FXML Application project that I've created even before installing the plugin opened up, and so did the main FXML file. I was already on the Design tab. Then this error showed up. This is actually the second time. Nothing seems to be broken.
