Follow-up Comment #5, bug #51919 (project octave):

I have another aspect: the directory under consideration 
is called initial_java_dir in the code in ov-java.cc. 
Thus I call it here initial java dir. 
If you have a look in the code (initial_class_path), 
it plays *three* roles: 
* where octave.jar resides which is the initial section of the classpath 
* where the file javaclasspath.txt resides which defines the installation wide
portion of the classpath which comes after the project wide and after the
user-wide one. 
* where the file java.opts resides containing the (installation wide) options.


All these three files must be moved if the initial java dir is changed. 
I think it is easy to document this: 

If OCTAVE_JAVA_DIR is not set, this is the directory 
where javaaddpath.m resides 
which can be found out by 'which javaaddpath' 
Otherwise, the java directory is given by OCTAVE_JAVA_DIR. 

Then one has to document the three roles and that's it. 

In further steps, we can try to improve this, 
but i think the first step would be to add this piece of information to the
documentation. 

I would like to prepare a patch if you agree.
