Just been through the process of upgrading our platform to the latest eclipse version from 3.x to 4.x with compatibility mode enabled (there's no pure e4 stuff).

Custom toolbars that were declared within the Extensions org.eclipse.ui.menu are duplicated when rendered. So if there was 1 toolbar containing 3 buttons declared in the extentions, there are now 2 toolbars containing 3 buttons rendered on screen. The duplication is sequential; So one full set of all toolbars, followed by all the duplicates.

Any thoughts on what could cause this duplication when migrating?

It sounds like bug 413492, which can occur when the app is killed or crashes. You can run with `-clearPersistedData` to throw away the .../.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi file.

Thanks for the quick reply and link to information!

I tried the -clearPersistedData, I may have done it incorrectly, but ultimately I wiped the runtime workspace I was working in and now things are back to normal.

For a second there my entire concept of EMF came crashing down all around me. Yikes! :-)
