Bug 576333 - [performance] optimize EclipseContext.localValues EclipseContext.isSetLocally is a hotspot during open java editor. Avoid synchronizedMap by using a ConcurrentHashMap for EclipseContext.localValues. Since ConcurrentHashMap does not allow null values it is wrapped. Null values are substituted by a neutral value. Speeds up EclipseContext.localValues by factor ~ 4.
