b130 MethodHandle weirdness?

[Ben Evans]

Hi,

I've noticed some oddities with b130 MethodHandles (this is x64 Ubuntu):

        private void foo() {
                System.out.println("Foo!");
        }

        private void run(String[] args) {
                MethodHandle mh;
                MethodType desc = MethodType.methodType(void.class);

            try {
                mh = MethodHandles.lookup().findVirtual(getClass(), "foo",
desc);
            } catch (NoAccessException e) {
                throw (AssertionError)new AssertionError().initCause(e);
            }

            try {
                        mh.invokeExact();
                } catch (Throwable e) {
                        e.printStackTrace();
                }
        }

Compiling with javac works fine, but on running:

bje@bje-desktop:~/projects/java_scratch/src$ java
-XX:+UnlockExperimentalVMOptions -XX:+EnableMethodHandles
-XX:+EnableInvokeDynamic com/db/java7/test/MHTest
java.dyn.WrongMethodTypeException: ()V cannot be called as ()V
        at com.db.java7.test.MHTest.run(MHTest.java:33)
        at com.db.java7.test.MHTest.main(MHTest.java:42)

bje@bje-desktop:~/projects/java_scratch/src$ java -version
java version "1.7.0-ea"
Java(TM) SE Runtime Environment (build 1.7.0-ea-b130)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b02, mixed mode)

Any ideas?

Thanks,

Ben
