Please move accordingly, I have no idea, where org.netbeans.core.browser.webview.ext is in Issuezilla.
Comment 3 Stanislav Aubrecht 2012-08-28 14:31:41 UTC 
WebKit debugger should check if the browser is still available (wasn't closed)
Comment 4 Jan Stola 2012-08-28 16:59:21 UTC 
I skimmed over the problematic code and I don't see a reason to obtain the location of the browser pane directly from the WebEngine (especially from a thread that is not a JavaFX thread). The location can be obtained from the browserImpl safely (without the need to care about the state of the browser pane) instead.
