28 * @summary Run the LambdaEagerInitTest.java test in static CDS archive mode.
29 * Create a custom base archive with the -Djdk.internal.lambda.disableEagerInitialization=true property.
30 * Run with the custom base archive with and without specifying the property.
31 * With the disableEagerInit set to true during dump time, lambda proxy classes
32 * will not be archived. During runtime, lambda proxy classes will not be loaded
33 * from the archive.
34 * Run with the default CDS archive, lambda proxy classes will be loaded
35 * from the archive if the property is not set.
36 * @requires vm.cds
37 * @library /test/lib /test/hotspot/jtreg/runtime/cds/appcds test-classes
38 * @compile ../../../../../lib/jdk/test/lib/Asserts.java
