[news.eclipse.platform.rcp] Hyperbola does not run anymore with RC1 ?

[Stéphane Fournier <stephane.fournier@xxxxxxxxxxxxxxx>]

Hi,

I got the hyperbola application at the EclipseCon, it was perfectly 
running with RCP M5a & M6. I am using the M7 & RC1, I get an exception 
when I try to open ChatEditor with any contact.

Does anyone have an idea to figure out this issue ?
