When will invokedynamic be available in the standard JDK?

Question

I'm eager to start working with dynamic languages on top of Java.

How long before this is part of the standard JDK?

Answer 1

When Java 7 is released. Currently, best guess is late 2010, but subject to change.

Keep an eye out. Last mention of JSR-292 was here, about 2 weeks ago.

Answer 2

Java language does not support dynamic language. However, you can use invokedynamic instruction in your java program with some library, like asm.
