Description Anthony Hunter

When using one of the new GMF Runtime 1.4.1 builds, a catastrophic issue occurs that you cannot open an existing diagram or create new shapes from the palette. Can be duplicated on a geoshapes diagram and create a dropshadow rectangle.

The problem is caused by the latest GMF 1.4.1 builds.

I can duplicate a similar issue by using the Eclipse GMF Geoshapes example and dropping a shadow rectangle on the diagram.

I took Helios GA and the Geoshapes example is fine.

As soon as I install only the GMF Runtime 1.4.1 build, I get the error:

The problem is with the MANIFEST.MF in org.eclipse.gmf.runtime.draw2d.ui_1.4.1.v20100720-0030.jar . The problem has nothing to do with the code changes submitted in GMF.

Somehow 
Bundle-ActivationPolicy: lazy
was removed from the plugin when we incremented the bundle service version.

It would appear Anthony mistakenly clicked the "Activate this plug-in when one of it's classes is loaded" when activating the editor and then blindly committed the change.

Fixed in HEAD and R1_4_maintenance
