This article contains a code sample that demonstrates how to register a bootstrap method: http://java.sun.com/developer/technicalArticles/DynTypeLang/ And yes, the valid signature is: CallSite myBootstrapMethod(Class caller, String name, MethodType type) > Thanks, > > Sander > cheers, Rémi --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
