I was just going to post the same. I received this response from Oracle support:
We have received the below information, that I hope it answers your question:
Exam 867 is an assignment resubmission that should only be used if the assignment is not passed on the first attempt. This exam is also retiring on 31-Aug.
865 and 866 are retiring on 31-Aug as well. This is being updated on the website. After 31-Aug, candidates will no longer be able to take any of the exams that earn the OCM for
Java EE6.
Please let me know if further clarification is needed.
