that helps if the argument types are known and there is an exact match to a method. It helps because in that case we can save the casting and converting plus the checks to see if we even have to do that. Yes. But currently that is not the case. And it won't change for Groovy2, maybe for a later Groovy.

I see, I will try that out. bye Jochen _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
