[armedbear-devel] integrating abcl into Protege

Putting that code in system.lisp isn't going to help the finding of
boot.lisp which needs to happen first to bring the interpreter up.
That said, having a hook in the build process so that users can dump
arbitrary forms to system.lisp isn't a bad idea.
I think the right way to handle the OSGi context is that we need a way
to specify that *LISP-HOME* (confusingly set via the abcl.home Java
property) cannot be set to a pathname, so all loading of system files
has to occur by using the getResource() method of the classloader that
instantiated Lisp.class. That OSGi code should install a jar handler
for the URI scheme which the Pathname code should use automatically,
but maybe it's associated with a different class loader of something.
We should probably assert that TRUENAME returns something after we
think we have a pathname, falling back to NIL before we pass to the
load syst fole routine. When I get to a computer tommorrow I can whip
out a quick patch to try, but it would be better if you could provide
some idea of the code your trying for the Protege plugin—which I
think is RCP based if I remember correctly—so I can test a bit.
