Re: [jdt-dev] JDT and javac

["Alexander Kriegisch" <alexander@xxxxxxxxxxxxxx>]

My two cents from an AspectJ compiler (JDT Core fork) perspective: This is bad news for us, because it means that we either need to give up native AspectJ syntax completely in favour of the less powerful annotation syntax or create a new fork based on OpenJDK's javac, both of which will have a huge impact one way or another. This statement is true, if it also means that ECJ will go towards its own end of life. If the announcement is about the front-end only and I misunderstood, by all means feel free to correct me.

Independently of AspectJ, I think that the move is actually a smart one in the grand scheme of things. If only it would not affect us... ;-)
