If you are not sure which mailing list is the right one, use jikesrvm-researchers. Do not post the same message to multiple mailing lists.
Please introduce yourself when posting for the first time. You should also state your affiliation (e.g. your university) if it's not obvious from your email address.If you are new to the Jikes RVM and have a question about modifying the Jikes RVM, please tell us what you want to do (i.e. your goal) before stating your concrete problem. This will give the list members enough context to suggest different approaches.
