Singletons
The following classes were changed to work in session scope, using the SessionSingletonBase class provided by RWT:
org.eclipse.ui.internal.progress.AnimationManager.AnimationManager
org.eclipse.ui.internal.progress.BlockedJobsDialog.BlockedJobsDialogProvider
org.eclipse.jface.resource.JFaceResources.ColorRegistryStore.ColorRegistryStore
org.eclipse.ui.internal.WorkbenchPlugin.DecoratorManagerStore.DecoratorManagerStore
org.eclipse.rap.demo.controls.DefaultButtonManager.DefaultButtonManager
org.eclipse.jface.resource.JFaceResources.FontRegistryStore.FontRegistryStore
org.eclipse.jface.resource.JFaceResources.ImageRegistryStore.ImageRegistryStore
org.eclipse.ui.internal.browser.WorkbenchBrowserSupport.InstanceHolder
org.eclipse.ui.internal.registry.PerspectiveRegistry.PerspectiveRegistry
org.eclipse.ui.internal.WorkbenchPlugin.PerspectiveRegistryStore.PerspectiveRegistryStore
org.eclipse.ui.internal.progress.ProgressManager.ProgressManagerProvider
org.eclipse.ui.internal.progress.ProgressViewUpdater.ProgressViewUpdater
org.eclipse.jface.resource.JFaceResources.Registries.Registries
org.eclipse.ui.internal.util.SessionSingletonEventManager.SessionSingletonEventManager
org.eclipse.jface.databinding.swt.SWTObservables.SWTObservables
org.eclipse.jface.internal.databinding.provisional.swt.SWTUtil.SWTUtil
org.eclipse.ui.internal.WorkbenchPlugin.ThemeRegistryStore.ThemeRegistryStore
org.eclipse.ui.internal.registry.ViewRegistry.ViewRegistry
org.eclipse.ui.internal.WorkbenchPlugin.WorkingSetManagerStore
org.eclipse.ui.internal.WorkbenchPlugin.WorkingSetRegistryStore.WorkingSetRegistryStore
Due to some restrictions on the SessionSingletonBase class it was necessary to extend SessionSingletonBase. Because of this there are a lot of inner classes or ugly constructs like the SessionSingletonEventManager, which allows to let the Workbench become session aware. This isn't necessary anymore and the code could be refactored to be much more cleaner, for example:
public static final Workbench getInstance() {
return ( Workbench )SessionSingletonBase.getInstance( Workbench.class );
}
