It's possible you have a corrupted prj.el file, especially if it was
created with an older version of the JDE. (Newer versions fix the problem,
I think). The corruption is this: the prj.el file has two or more instances
of the (jde-set-variables ...) form that sets the variables to save values,
e.g.,
(jde-set-variables
...
)
(jde-set-variables
...
)
What happens is that when you save variables in the project file, the save
command replaces only the first instance of the form, the one with the new
values. Then, when the prj.el file is reloaded, all the forms get executed
and the last one (with the old settings) wins.
The solution is to delete all but the first (jde-set-variables ...) form in
the prj.el file. This problem should not occur with prj.el files created in
JDE 2.1.9.
