 * @summary converted from VM Testbase vm/mlvm/indy/func/java/thisAsArgument.
 * VM Testbase keywords: [feature_mlvm]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test is written for a CR 6927831:
 *     InvokeDynamic throws NoClassDefFoundError in the following test:
 *     package test;
 *     import java.dyn.InvokeDynamic;
 *     import java.dyn.InvokeDynamicBootstrapError;
 *     public class Self {
 *       public static void main(String[] args) {
 *             try {
 *                 InvokeDynamic.<void>greet(new Self());
 *             } catch ( InvokeDynamicBootstrapError e ) {
 *                 System.out.println("TEST PASSED");
 *             } catch ( Throwable t ) {
 *                 System.err.println("Oops!");
 *                 t.printStackTrace();
 *             }
 *         }
 *     }
 *     ...when it is launched with -classpath:
 *     $ java -classpath bin test.Self
 *     Oops!
 *     java.lang.NoClassDefFoundError: test/Self
 *         at test.Self.main(Self.java:10)
 *     If we replace -classpath with -Xbootclasspath:
 *     $ java -Xbootclasspath/a:bin test.Self
 *     TEST PASSED
 *
