I agree with Jim.  From what I recall, Sun conformance testing takes the
approach that the "gold standard" for Java is not the JavaDoc but the
behaviour of their JDK reference implementations.  Assuming that we want 
to "conformant", we should follow Sun's definition of what this means.

Besides, it is unrealistic to expecting people to code applications to
assume >>only<< what the JavaDocs says.  Most people don't write code
with the JavaDoc.  If they tried to, they'd probably fail because:

  1)  the javadoc is often incomplete, occasionally misleading and
      sometimes plain wrong, and

  2)  your average joe programmer has difficulty reading/comprehending
      precise specifications.

So, this sounds like a real bug.  The way to be sure would be to distill
it onto a Mauve testcase so that it can be run against various Sun JDKs.
