public final class NativeImageSystemClassLoader
extends SecureClassLoader

NativeImageCustomSystemClassLoader is a minimal ClassLoader that forwards loading of a class to a NativeImageSystemClassLoader.nativeImageClassLoader ClassLoader. If such delegate is null, then NativeImageSystemClassLoader forwards the class loading operation to the default system class loader. This ClassLoader is necessary to enable the loading of classes/resources during image build-time. This class must be used as a replacement for ClassLoader.getSystemClassLoader() and its parent must be the default system class loader. The delegate is set to an instance of NativeImageClassLoaderSupport.
