You should use the JDE->Help->Submit Problem Report command. It gathers
the information about your system that experience has shown to be
the most useful in debugging JDEE programs.

This has nothing to do with your problem. extent-list is defined
only in XEmacs. The JDEE has lots of code that refers to XEmacs-only
symbols. The Emacs compiler doesn't know about them so it complains.

The error occurs because Emacs returned nil when the JDEE tried to get
the file name for the current Java source buffer. The only way I know
this can happen is if you try to run the jde-compile command
with a buffer selected that is not a Java buffer and does
not have a file associated with it.

Yes. They mostly mean that the JDEE tries to support both Emacs and
XEmacs and both editors define symbols that the other does not know
about and hence the JDEE refers to symbols that the Emacs compiler
does not know about and that the XEmacs compiler does not know
about. Occasionally they can indicate a real problem but I don't of
any such case with the current release.
