FTR, there's a good smoke test for the method handles part of JSR 292 in the
JDK sources:
davinci/sources/jdk/test/java/dyn/MethodHandlesTest.java
Running the test requires JUnit 4.5.
$JSR292_JAVA_HOME/bin/java -ea -esa
-XX:+{UnlockExperimentalVMOptions,EnableMethodHandles}
The sources are changing rapidly at this point; I'm working on invokeGeneric.
If you send me a JAR which which can run stand-alone, I can use it as a
regression test.

Yeah, I suppose this is
Also worth noting is that if you specify a specific return type (i.e. boolean)
at the call site, MOP will ensure that whatever method ends up invoked, the
return value is converted (either using built-in JVM conversions, or even your
own language-specific ones if you provide a

The dynalang-invoke's own test suites fail quite massively when I make the

BTW, what's the current state of the art for emitting .java with an
invokedynamic in it? Duby also has a .java backend, so I'll need to
add indy support there as well (somehow).
