> The default LauncherClassloader is not synchronizing its loadClass method correctly. As it just delegates to the findClass of the URLClassloader it extends, it needs to at a minimum lock on the classname it is trying to load - otherwise, it is possible that it will catch a LinkageError if the same class load is happening concurrently.
