Howdy,

I'm endeavoring to update the target platform for an Eclipse RCP app based upon Eclipse 3.7.

I've added all the Eclipse deps to Photon version and am getting the following startup error:

!ENTRY org.eclipse.e4.ui.workbench 4 0 2018-09-05 15:58:31.103

An error has occurred. See the log file

Of course there is no Application.e4xmi file, as it was an Eclipse 3.7 RCP app. But...I've been away from RCP for a while...I had thought that there was a compatibility mode for RCP 3.x plugins...or perhaps that has gone away? Is there any way to just use the old product config and app plugin.xml and run on Eclipse e4 now?...e.g. with some legacy .e3xml file, or perhapsthe old rcp stuff in plugin.xml be converted to Application.e4xmi and then be run?

Thanksinadvance for any information or pointers,

Scott
