 * @bug 8257241
 * @summary Run the LambdaEagerInitTest.java test in static CDS archive mode.
 *          Create a custom base archive with the -Djdk.internal.lambda.disableEagerInitialization=true property.
 *          Run with the custom base archive with and without specifying the property.
 *          With the disableEagerInit set to true during dump time, lambda proxy classes
 *          will not be archived. During runtime, lambda proxy classes will not be loaded
 *          from the archive.
 *          Run with the default CDS archive, lambda proxy classes will be loaded
 *          from the archive if the property is not set.
 * @requires vm.cds
 * @library /test/lib /test/hotspot/jtreg/runtime/cds/appcds test-classes
 * @compile ../../../../../lib/jdk/test/lib/Asserts.java
 * @run main/othervm LambdaEagerInit
