John,
thank you a lot for such an effort with that example! I will try this later.
But first, I have few non-technical questions about JSR-292 in JDK7.
(Sorry, I'm not sure, if these questions has been asked a lot already.)
1) Which JSR-292 features will people be able to use with standard

Hello!
Sorry, but I seem not to understand the description of @BootstrapMethod javadoc.
I declare a class with a static method (which returns a CallSite).
The class from which InvokeDynamic is performed is annotated with the new
annotation.
Error is: java.lang.IllegalStateException: no bootstrap
Remi, with your suggestion and the workaround the bug (by returning int),
here the updated "benchmark". Works, but still much slower than usual
reflection.
The new code is under doDynSyntaxSpread() and displayed as "invoke dynamic
syntax: spread".
Output is at the end.

Ok, I extended my "benchmark" to support a method handle with spread args,
and this part slower than everything else :(
Note: I use Object[] for spread arguments, because in my real-world scenario,
as mentioned before, I would need any possible method signature to work.
Sadly, I still couldn't fi

Hm, strange, I thought Netbeans would use the usual javac, but now I guess it
uses
some API calls to compile files. Because using javac from command line works
indeed!

Hello again!
For that compiler error which you could reproduce, will you file a bug report,
or is the API that much under change currently, that it's not relevant yet?
Sorry, the proposed workaround produces same error for me.
For the use case "calling a method whose signature is unknown prior t
Remi, thank you a lot for such a quick reply!
I tried to do what you suggested, but it keeps failing.
Note, that I don't use some customized build, but instead, as also mentionen in
previous mail, JDK7 b116.
Could you please try the code by yourself? It's a single class.
Thanks again!

Hello, everyone!
I couldn't find information about several issues, so I'll ask here for help:
I'm using JDK7 b116.
When using MethodHandle.invokeExact(...), I can only invoke a method,
which signature is "Object (Object[])", anything else fails with:
WrongMethodTypeException: ()V cannot be c
