Comment 2 Petr Jiricka 2012-08-01 12:00:30 UTC 
I was also using JavaFX 2.2 b19. Note that after I got this exception, the IDE stopped responding after a while, and processor usage went to 100%. I could not even generate a thread dump. 
Changing priority to P2.

Though I am using non-final builds of JDK and JavaFX - could that be a problem?

This problem isn't related to WebView, it's reproducible with an empty JavaFXPanel.
