Hi,
I have made some progress:
wizziewol-ln:src lov080$ $b/javac -source 1.7 -bootclasspath $m/rt.jar
-g -Xlint invokedynamicvirgin/Hello.java
Works - hurray! You need both -source 1.7 and -bootclasspath $m/rt.jar
(-g and -Xlint aren't needed). Presumably this is a bug in the 1.7
compiler that doesn't set the defaults properly. Same result with both
Ben and Attila builds. However I still have a problem with running the
code, e.g. with Attila's build:
wizziewol-ln:src lov080$ $b/java -showversion -ea -XX:
+EnableMethodHandles invokedynamicvirgin.Hello
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-
aszegedi_2009_04_19_15_49-b00)
OpenJDK Server VM (build 15.0-b02, mixed mode)
Hello, world (from a statically linked call site)
Hello, world
Exception in thread "main" java.lang.IncompatibleClassChangeError
at invokedynamicvirgin.Hello.main(Hello.java:30)
Identical result on both builds. The code in question is:
public static void main( String... av ) {
if ( av.length == 0 ) { av = new String[] { "world" }; }
greeter( av[ 0 ] + " (from a statically linked call site)" );
for ( String whom : av ) {
greeter.<void>invoke( whom ); // strongly typed direct call
// previous line generates invokevirtual MethodHandle.invoke
(String)void
Dynamic x = whom;
x.hail(); // weakly typed invokedynamic
// previous line generates invokedynamic
// MethodHandle.invoke(Dynamic)Dynamic
}
}
And line 30 is the x.hail() line. The code is Simple Example from:

Can you guys run this code, if so, what are your command line options?
Thanks,
-- Howard.
