Double-Checked Locking in Agent Plugin code

XMLWordPrintable

        The method createSingleton() in PresetRepositoryFactory.java relies on double-checked locking, an incorrect idiom that does not achieve the intended effect.

         

        private static PresetRepository singleton; 
public static PresetRepository createSingleton() { 
    if (singleton == null) { 
         synchronized (PresetRepositoryFactory.class) {
            if (singleton == null) { 
               singleton = create(); 
             } 
           } 
     } 
     return singleton;
