NASA World Wind There are two substantial advantages to World Wind. Because the singleton initialization is what's in progress when the logging call is made the singleton instance is still null, and this eventually causes a NullPointerException. This causes a static initializer to fire in the Logging class, which in turn makes a series of static calls in the Configuration class that eventually want the Configuration instance's singleton to have been fully initialized and assigned. ![]() The problem manifests if execution ends up e.g. If things go wrong during the Configuration class's constructor - for example, a faulty resolution of lower-level classes such as XPath-related stuff, which was the case here at our site - it can expose a circular dependency in the Configuration class between its constructor and its own singleton instance. ![]()
