status behind JDK-8149738

[Guru Hb]

Hi Matthieu,

Crash is due to Mouse event is not handled correctly from WebView context.

Could you please provide these details.

1. What Content is loaded to WebEngine. (Live webpage or custom content)
2. which mouse event lead to crash (Right / left click, Double click, 
Scroll)
3. W.r.t 2nd point, is there a pop-up dialog exist ? or what was the 
html element under which mouse event triggered (Input element, Editable 
div, Form elements, Image , upload dialog, table,etc).
4. Any Modal Dialog used in the application under test , which will be 
used as a call back to an event from WebEngine ?

With above details , i could derive a test content / scenario to 
re-produce the crash.

Thanks,
Guru
