I have heard of no such thing and I doubt they would do such a thing. In general, between each edition of the exam, there are a number of versions of
Java that come and go - Java 1.3 never had an exam specifically for it. It seems as if Sun just finished getting the 1.4 exam in place and I imagine it will be some time until they're ready to make a new version of that exam.
Of course, I don't work for Sun and I don't help with the exams, so I can only tell you what I think and what I've heard. I've heard nothing, so this is just what I think.
