Sorry, I should have been more explicit.  I was thinking that those 2
spaces you're seeing might really be a TAB character.  If so, it would
look like 8 spaces in less or other editors.

If you put the cursor in those 2 spaces, then do "C-x =", it will tell
you what's there.  If it is indeed a TAB character, check the value of
the Emacs variables `tab-width' and `indent-tabs-mode' (using "C-h v").

If this isn't the problem, then could you do "C-c C-b" from the java
buffer, to dump the internal state of java-mode.  Post that dump here,
and we'll probably be able to see what's going wrong.
