This allows a plain old virtual method invocation in the Java language to effect invocation of a dynamically typed method, via the java.lang.invoke.MethodHandle API and an upgraded invokevirtual instruction [2].

In particular, the latest version of OpenJDK 7 has no major performance issues (that I'm aware of) as compared to the Oracle binary.

Would be nice to have at least a bug report from them rather than just scaring messages. I think this is probably a good reason to use a different IDE though.

Here is a proposal from that time frame: https://wiki.openjdk.java.net/display/mlvm/DynamicJava Nothing like this exists or was built in any usable way. Untyped or "duck typed" invocation of objects can be done easily enough with third-party libraries, or with reflection, or using a dynamic language like JavaScript or JRuby or ${your_favorite_jvm_language}. In my opinion, Java the language is unlikely to support such a thing in the near future, since there are many reasonable alternatives. — John </pre> John Rose 2013-06-14T02:05:48 http://permalink.gmane.org/gmane.comp.java.openjdk.general/3295 <pre>Hi, A couple of years ago I downloaded an experimental build of JDK with invokedynamic support and it contained a class (DynamicObject?) that any method could be invoked on its subclasses without any compile time errors. Does this class still exist? I can't find it anymore in the API docs.

Novel concepts and abstraction mechanisms including aspect-oriented techniques are a focus point for improvements in the support for modularity. The scope of this effort covers all perspectives on software systems in all their life-cycle phases, for instance application domain analysis, programming language constructs, formal proofs of system properties, program state visualization in debuggers, performance improvements in compiler algorithms, etc. As the premier international conference on modularity, Modularity continues to advance our understanding of</pre> danilo.ansaloni-BHDiRLqP7qo< at >public.gmane.org 2013-05-30T16:43:10 http://permalink.gmane.org/gmane.comp.java.openjdk.general/3293 <pre> Hi Elisa, Welcome! For the record, together with the GNU Classpath and IcedTea communities we decided to do this experiment, and allocated one resource to help students to be introduced to OpenJDK development. The project is still part of the GNU Classpath umbrella and will be followed by GNU Classpath people. If the experiment will succeed, we may try to turn next year into a proper organisation fully dedicated to OpenJDK. I will be mentoring Elisa, and the code will be probably hosted on the icedtea server once ready for use (although for the time being we will develop the code on an external repository until everything is set correctly). Once again, welcome Elisa! Cheers, Mario </pre> Mario Torre 2013-05-28T15:52:06 http://permalink.gmane.org/gmane.comp.java.openjdk.general/3292 <pre>Welcome Elisa!

I'm Elisa and I'm taking part to Google Summer of Code 2013 with GNU Classpath project. I proposed one of the projects, the new Gtk3 Look and Feel for OpenJDK, and it was accepted. I'm looking forward to start this project. It's a big opportunity for test my knowledge and work this summer in my job field.
