Tools used to import Rhapsody Model, RSA model, or converting SysML 1.1 into SysML 1.4 plugin, could be used without opening a Papyrus Diagram. These tools uses a property view configuration displayed in a Dialog, but we can't access to the ConfigurationManager instance (deadlock). Pausing the runtime, we saw : - the Rhapsody import is waiting for org.eclipse.papyrus.views.properties.runtime.ConfigurationManager.getInstance(). (main thread, upper in the stack, there is a readAndDispatch call) - ConfigurationManager.getInstance() is already locked by an other thread, which is loading sequence diagram (we are blocked waiting Display to execute a syncExec in org.eclipse.gmf.runtime.diagram.ui.preferences.AppearancePreferencePage.setDefaultFontPreference(IPreferenceStore). ) Removing the view property contribution of the sequence diagram fix the bug, but is probably not the good solution. We don't have the problem when a Papyrus model is already opened.

New Gerrit change created: https://git.eclipse.org/r/89555
Generating a property view for a profile seems impacted too
I renamed the bug, because it is not linked to the SequenceDiagram, it is a more general problem. The problem has already been identified in bug 481830, maybe the same kind of fix could help us.
