CEDET

I have two files:

~/tmp/A/src/A.java: public class A {}
~/tmp/B/src/B.java: public class B {}

I start Emacs.  I do C-x C-f ~/tmp/A/src/A.java RET.  All is fine.  I
then do C-x C-f ~/tmp/B/src/B.java RET.  Then I get the message
"Buffer B.java was not set up for parsing", and the modeline
indicators are wrong, and JDEE does bad indenting.

The same thing happens if I open B first, then A.  Then B.java will
work fine but A.java will exhibit the "not set up for parsing"
message.

The effect of this is that I can only work on one project in a given
Emacs instance.  The first *.java file I open determines the project.

I use JDE 2.3.3, too, that seems to be relevant.

Can anyone help me investigate further?  I have no idea what to do
next.
