31 * DESCRIPTION
32 * The test is written for a CR 6927831:
33 * InvokeDynamic throws NoClassDefFoundError in the following test:
34 * package test;
35 * import java.dyn.InvokeDynamic;
36 * import java.dyn.InvokeDynamicBootstrapError;
37 * public class Self {
38 * public static void main(String[] args) {
39 * try {
40 * InvokeDynamic.<void>greet(new Self());
41 * } catch ( InvokeDynamicBootstrapError e ) {
42 * System.out.println("TEST PASSED");
43 * } catch ( Throwable t ) {
44 * System.err.println("Oops!");
45 * t.printStackTrace();
46 * }
47 * }
48 * }
49 * ...when it is launched with -classpath:
50 * $ java -classpath bin test.Self
51 * Oops!
52 * java.lang.NoClassDefFoundError: test/Self
53 * at test.Self.main(Self.java:10)
54 * If we replace -classpath with -Xbootclasspath:
55 * $ java -Xbootclasspath/a:bin test.Self
56 * TEST PASSED
57 *
58 * @library /vmTestbase
