strange failure in javaaddpath

[Daniel Oberhoff]

Hi All,

I just wanted to try out the new jhandles plotting thing. I am on  
osx, so I had to whack the configure scripts of java and jhandles a  
little, basically hardcoding some paths and version numbers, but then  
they go through. But when installing jhandles I get soem unspecified  
error in javaaddpath. Now I experimented and the error _always_  
happens when

java_invoke ("org.octave.ClassHelper", "addClassPath", new_path);

which is the core functionality of javaaddpath, is called from within  
a function. i.e.

octave:3> java_invoke ("org.octave.ClassHelper", "addClassPath", "/");

works but

octave:2> function test;java_invoke ("org.octave.ClassHelper",  
"addClassPath", "/");end;test

gives

error: called from `test'

??? what is different inside the function that can make java_invoke  
fail so mystically?
