First, did you know about "pkg load all"?

Further package-specific ideas below:

This is probably normal, I don't use the plot package, I have no idea
what it's useful for.

You should not have the java package installed in Octave 4.0 or higher.
The java functions have been integrated into Octave and the package is
now no longer needed. It may not be hurting yet, but it's definitely not
helping.

When you see undefined symbols errors from oct-files, it usually means
the oct-file needs to be recompiled. Try uninstalling and reinstalling
the image package. In this case my guess is you installed the image
package under Octave 3.8 and then started using 4.0 without reinstalling
the package.

So in summary, uninstall java, reinstall image, and try "pkg load all"
and see if you get the desired outcome.
