Bug 281744 ReflectionContributionFactory should log something when create(String, IEclipseContext) is unsuccessful
I made a mistake defining my MContributedPart's URI property but was not informed of this in the logs. This is because ReflectionContributionFactory's create(String, IEclipseContext) doesn't log anything if the bundle could not be retrieved.
bundles/org.eclipse.e4.ui.workbench/src/org/eclipse/e4/workbench/ui/internal/Activator.java
return (Location) locationTracker.getService();
	}
	public void start(BundleContext context) throws Exception {
		activator = this;
		this.context = context;
		executorTracker = context.registerService(ISchedulingExecutor.SERVICE_NAME,
				new JobExecutor(), null);
		EclipseContext.DEBUG = getDebugOptions().getBooleanOption(
				PI_WORKBENCH + Policy.DEBUG_CONTEXTS, false);
		EclipseContext.DEBUG_VERBOSE = EclipseContext.DEBUG
				&& getDebugOptions().getBooleanOption(PI_WORKBENCH + Policy.DEBUG_CONTEXTS_VERBOSE,
						false);
	}
	public void stop(BundleContext context) throws Exception {
		if (pkgAdminTracker != null) {
			pkgAdminTracker.close();
			pkgAdminTracker = null;
		}
		if (locationTracker != null) {
			locationTracker.close();
			locationTracker = null;
		}
		if (executorTracker != null) {
			executorTracker.unregister();
			executorTracker = null;
		}
		if (debugTracker != null) {
			trace = null;
			debugTracker.close();
			debugTracker = null;
