v4.6.0: Unable to 'register' a context menu more than once in a part (on 2 different widgets) [message #1739312]

Hi,
In short, with eclipse v4.5.2, it is possible to attach the same popupmenu to more than one component/widget in the same "part" by using EMenuService.registerContextMenu() without problem

This does not work anymore with v4.6.0. With v4.6.0, the popupmenu only appears on the first registered component

This is described in bug #496695

This forbids me to upgrade my eclipse-rcp application to v4.6.0

Q:
- Am I the only one hit by this bug ?
- Is there a workaround?
- Was it "legal" to register the same popupmenu multiple time on different widget (in my case different "Table"s from multiple "TableViewer"s present in the part?). If not how to do it the "legal way"?
Thx

I found that a line in class org.eclipse.e4.ui.internal.workbench.swt.MenuService in method registerContextMenu(Object parent, String menuId) disappeared between v4.5.2 and v4.6.0
Adding back the missing line make it work again!
See the comments in bug #496695
Could someone validate that this is the cause of the regression and make the change in eclipse?
Thx
