ClassInitializer
public class ClassInitializer (Code)

This utility class allows for initialization of all classes at startup to avoid initialization delays at an innapropriate time.

Note: Users might want to disable logging when initializing run-time classes at start-up because of the presence of old classes (never used) in the jar files for which initialization fails. For example:[code] public static main(String[] args) { LogContext.enter(LogContext.NULL); // Temporarely disables logging errors and warnings. try { ClassInitializer.initializeAll(); // Initializes bootstrap, extensions and classpath classes. } finally { LogContext.exit(LogContext.NULL); // Goes back to default logging. } ... }[/code]
