Example 1 with ImageClassLoader

use of com.oracle.svm.hosted.ImageClassLoader in project graal by oracle.

the class NativeImageClassLoaderSupportJDK11OrLater method createModuleLayer.

     * to resolve against system modules that are not used by the moduleLayer in which the
     * image-builder got loaded into. To do so we use {@link upgradeAndSystemModuleFinder} as
     * {@code ModuleFinder after} in
     * {@link Configuration#resolve(ModuleFinder, ModuleFinder, Collection)}.

     * accessed with a single classloader so we can use it for {@link ImageClassLoader}.
