This problem seems to have gone away, however...

When starting up and restoring the desktop emacs uses 100% of one of the
cores, and after 1h of starup still hasn't completed (and this is a
pretty fast machine).

Does anyone know what causes this?  Is emacs-desktop restore and JDEE
just a bad mix?

One more datapoint: this is when using remote X display over an SSH
connection with X forwarding.

Thanks!
