Some people say that the Eclipse support for alternative JVM based languages is not best in class. Therefore I think it is great news that Olivier Thomann from the JDT team indicated that might open up JDT to better support Java like languages.
I think this would be great and definitely a mayor step for the Eclipse IDE. As far as I understood the Scala IDE and the Groovy support could be heavily improved if the JDT could allow these environments to leverage the JDT infrastructure.
I believe these are great news for the interested people and the Eclipse ecosystem.
