[Octave-bug-tracker] [bug #42993] Octave's Java does not load Service-Provider-Interface classes

[Philip Nienhuis]

Follow-up Comment #1, bug #42993 (project octave):

Octave's Java implementation does have a few wrinkles, yes; some are mentioned
here in the task tracker: 
https://savannah.gnu.org/task/?12601.
I doubt if they will be solved in the near future as no one is working on them
at present.

If it may comfort you:
While building the UNO Java spreadsheet interface to LibreOffice, I had to
jump through a few hoops to get stuff together. Maybe you can get a first
impression of some required workarounds if you compare this (a formal Java
implementation):
https://wiki.openoffice.org/wiki/Documentation/DevGuide/FirstSteps/Example:_Working_with_a_Spreadsheet_Document

...with this (how it ended up in Octave (-Forge)):
http://sourceforge.net/p/octave/io/ci/default/tree/inst/private/__UNO_spsh_open__.m
...and...
http://sourceforge.net/p/octave/io/ci/default/tree/inst/private/__UNO_oct2spsh__.m

(esp. the queryInterface and PropertyValue stuff gave headaches)

Now these examples don't quite directly apply to your problem; but I think
they do show that workarounds can be found in unexpected places and
-directions.
