org.eclipse.jpt.ui.internal.wizards.JpaFacetActionPage.setUpRuntimeListener()throws a class cast exception due to its cast to ModifyFacetedProjectWizard.  IWizardPage.getWizard() should check for instanceof before making a cast.  In our scenario this wizard page is not in the ModifyFacetedProjectWizard.  Ideally you would get this property out of the datamodel using code like this:

		wc = (IFacetedProjectWorkingCopy) getDataModel().getProperty(
				IFacetDataModelProperties.FACETED_PROJECT_WORKING_COPY);
		if (wc != null) {
			// must do it manually the first time
			model.setProperty(RUNTIME, wc.getPrimaryRuntime());
			runtimeListener = new IFacetedProjectListener() {
				public void handleEvent(final IFacetedProjectEvent event) {
					model.setProperty(RUNTIME, wc.getPrimaryRuntime());
				}
			};
			wc.addListener(runtimeListener, IFacetedProjectEvent.Type.PRIMARY_RUNTIME_CHANGED);
		}


The working copy is in the datamodel and it would avoid the class cast issue when run in a wizard that is not that class.


Reproducible: Always
